Port Type

Displays the Port Type (Copper or SFP).

Description

It is used to configure the information description of this interface , which can be a description of usage, etc., with a maximum of 128 characters, and the characters limited to input are numbers 0-9 , letters az / AZ and special characters.

Port Enable

Set whether to enable the interface.

it is enabled by default.

Scheduled enabled

From the drop-down list, select the schedule for when the port (including physical and LAG ports) will be enabled.

Speed

Set the rate of the interface:

  • Ethernet port (Copper): the options are {Auto, 10Mbps, 100Mbps, 1000Mbps}, The default is auto-negotiation.

  • SFP/SFP+ port: the options are:

• GWN7801P Pro 2.5G SFP: 100Mbps, 1000Mbps, 2.5Gbps. Default: 2.5Gbps

• GWN7802P Pro/GWN7803(PL/PH) Pro SFP+: 100Mbps, 1000Mbps, 2.5Gbps, 10Gbps. Default: 10Gbps

• GWN7806PL/PH Pro SFP+: 100Mbps, 1000Mbps, 10Gbps. Default: 10Gbps

Notes:

  • When set to Auto, the rate of the interface is automatically negotiated between the interface and the peer port .

  • When configuring a fixed speed, ensure the peer port is set to the same value. Otherwise, the port may not function properly.

Duplex Mode

Set the duplex mode of the interface. The GE ports options are { auto-negotiation, full-duplex, half-duplex}. The default is auto-negotiation.

  • Auto-negotiation: The duplex state of an interface is determined by the auto-negotiation between the interface and the peer port.

  • Duplex: the interface send and receive data packets.

  • Half-duplex: interface can only send/ receive packets.

Notes:

  • Optical ports only support full-duplex mode.

  • When setting Duplex Mode manually (Duplex or Half-duplex), ensure the same mode is configured on the peer port. Otherwise, the port may not work normally.

Jumbo Frame

Specify the Jumbo Frame, the valid range is 1518-12288. Default is 9216

Flow Control

Set the flow control on the interface, the options are {Disabled, Enabled, Auto}. The default is Disabled.

After enabling it, if the local device is congested, it will send a message to the peer device to notify the peer device to temporarily stop sending packets, after receiving the message, the peer device will temporarily stop sending packets to the local and vice versa. Thus, the occurrence of packet loss is avoided.

Note: The optical port does not support auto-negotiation mode.

Port Basic Settings – Edit port

Port Group

The port group feature allows administrators to logically bundle specific ports together under one group with a corresponding group ID, this can be useful when classifying the switch ports for identifying the usage of each set of ports, for example, ports 1 to 8 can be set with ID 20, these will be the ports connecting Security devices.

Port group settings can facilitate quick batch settings for port group ports.

Port Group

Once the Port Group is created, it can ease up the process of selecting and tagging/untagging VLAN ports individually, Under Switching → VLAN, select the port group to be used for your VLAN

Port Group Selection

In addition, users can disable/enable specific ports based on the port group created, instead of going through each individual port selection separately:

Delete Port Group

Port Statistics

For monitoring or even sometimes troubleshooting, the Port Statistics displays in real time the flow of data with different units like Octets, Packets, Transmission Rate, and OurErrPackets. The option to clear all the statistics or a specific port is supported as well.

Port Statistics part 1

To view even more details like Etherlike (SNMP), RMON, and port Private MIB information.

Port Statistics part 2

Loopback Detection

By enabling the loop detection function of the interface, the interface periodically sends detection packets to check whether the packets are returned to the device, and then determines whether there is a loop in the device. If a loop is detected, the port is automatically shut down to eliminate the loop and ensure the normal operation of the network environment.

Note:

Interface Loopback Detection is not effective. If STP is enabled, because STP protection overrides interface Loopback Detection.

Loopback Detection

Port Auto Recovery

Port Auto Recovery helps recover a port after a specific delay that can be specified by the user. When the following functions of the port trigger the port down, the port automatically returns to the up state after the delay time:

Examples:

  • ARP packet detection: If the ARP rate in DAI exceeds the set value, the current port will be shut down.
  • STP BPDU Guard: In spanning tree, the port enables BPDU Guard. When this function is triggered, the port will be shut down.
  • Port Loop: When the port is self-looping and spanning tree is enabled, the port will be shut down.
  • ACL: When the ACL rule is matched and the action is shutdown, the port will be shut down.
  • Port Security: When the number of port MAC addresses exceeds the set number, the port will be shut down.
Note

When the recovery time is up and the port is back up, if the condition that triggers the down occurs again, the port will be shut down again.

Port Auto Recovery

LAG means Link Aggregation Group which groups some physical ports together to make a single high-bandwidth data path. Thus it can implement traffic load sharing among the member ports in a group to enhance the connection reliability.

There are two load balance modes on the GWN78xx Switches, either based on the MAC Address or based on the IP – MAC Address. And in terms of the type of LAG, there are either the static option or to use the LACP or Link Aggregation Control Protocol both of them are supported.

Link Aggregation Group

Load Balancing Mode

Select your Load balance mode.

MAC address – Aggregated group will balance the traffic based on different MAC addresses. Therefore, the packets from different MAC addresses will be sent to different links.

IP/Mac Address – Aggregated group will balance the traffic based on MAC addresses and IP addresses. Therefore, the packets from same MAC addresses but different IP addresses will be sent to different links.

Edit Group

Name: Enter the name of the LA Group.

Type: Use the drop down menu to specify the type for LAG.

  • Static– The static aggregated port sends packets over active member without detecting or negotiating with remote aggregated port.

  • LACP– The LACP aggregated ports place member into active only after negotiated with remote aggregated port for best reliability.

GE: Click on port to check / uncheck which ones will be part of this LAG.

Link Aggregation – LACP

MAC Address Table

The MAC address table records the correspondence between the MAC addresses of other devices learned by the switch and the interfaces, as well as information such as the VLANs to which the interfaces belong. When forwarding a packet, the device queries the MAC address table according to the destination MAC address of the packet. If the MAC address table contains an entry corresponding to the destination MAC address of the packet, it directly forwards the packet through the outbound interface in the entry. If the MAC address table does not contain an entry corresponding to the destination MAC address of the packet , the device will use broadcast mode to forward the packet on all interfaces in the VLAN to which it belongs except the receiving interface.

The entries in the MAC address table are divided into Dynamic Address, Static MAC Address, Black hole Address and Port Security Address.

Dynamic Address

the MAC address table is established based on the automatic learning of the source MAC address in the data frame received by the device. If the MAC address entry does not exist in the MAC address table, the device adds the new MAC address and the interface and VLAN corresponding to the MAC address as a new entry into the MAC address table. GWN78xx Switch will update the entry by resetting the aging time.

Aging Time:
Dynamic MAC address entries are not always valid . Each entry has a lifetime. The entries that cannot be updated after reaching the lifetime will be deleted. This lifetime is called the Aging Time. If the record is updated before reaching the lifetime, the aging time of the entry will be recalculated.

Notes

  • The value range is 0 or 60-1 000000, the default is 300. If it is set to 0, it means that dynamic MAC address entries will not be aged
  • Dynamic table entries are lost after system restart.

Dynamic MAC Address Table

Click on the “Refresh” button to update the table, or click on the “Add Static MAC Address” button to add the entry to the static MAC address.

Static MAC Address

This section allows the user to manually assign a MAC address to the MAC table. The configuration
result will be displayed on the table listed on the lower side of this web page.

Note

The static MAC address must be unicast.

VLAN

A virtual local area network, virtual LAN or VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical local area network (LAN), but it allows for end stations to be grouped together even if they are not located on the same network switch. VLAN membership can be configured through software instead of physically relocating devices or connections.

A user can click on “Add” button to add a new VLAN, also it’s possible to create many VLANs at the same time by specifying a range, for example (7-9) will create VLAN 7,8 and 9, or create different separated VLANs, for example (11,89) will create VLAN 11 and 89.

Note:

VLAN ID valid range is from 2 to 4094. VLAN 0,1 and 4095 are reserved for the system.

VLAN Port Settings Protocol Template

Port

Shows the selected Port.

Link Type

Select the Link Type:

  • Hyprid: Used for connection between switches, or switch and computer.

  • Access: used to connect the switch and the user terminal.

  • Trunk: used for interconnecting switches or connecting switches and routers, and can carry data frames of multiple different VLANs.

  • QinQ: This is an extended VLAN tagging technique where an additional VLAN tag is added, also known as “double tagging.” It allows Layer 2 tunneling and is often used by service providers to transport customer VLANs.

PVID

Enter the default VLAN ID.

Accept Frame Type

Specifies which types of Ethernet frames are accepted by the port. Options vary depending on the selected Link Type:

Hybrid:

  • All: Accept both tagged and untagged frames (default).

  • Tag Only: Accept only tagged VLAN frames; untagged packets will be dropped.

  • Untag Only: Accept only untagged frames; tagged frames will be dropped.

Access:

  • All: Only this option is available. Untagged traffic is mapped to the configured PVID.

Trunk:

  • All: Accept both tagged and untagged frames; untagged frames are assigned to the PVID (default behavior).

  • Tag Only: Accept only tagged frames; untagged traffic will be dropped (disables native VLAN).

QinQ:

  • All: Only this option is available due to double tagging structure.

Note: Setting Tag Only is the recommended method to disable native VLAN behavior on trunk and hybrid ports, providing better traffic control and increased security.

Ingress Filtering

Set whether to enable the inbound filtering function of the interface.

Ingress Filtering is only available for Hybrid port, and it’s enabled by default.

Note: Ingress filtering is a method used by enterprises and internet service providers (ISPs) to prevent suspicious traffic from entering a network.

VLAN Translation

 Allows translating one VLAN ID to another at the port level. It’s useful for scenarios where different parts of the network use different VLAN IDs but need to communicate with each other.

MAC VLAN

 Allows the switch to assign VLANs based on the MAC address of the incoming traffic. It can be used for more dynamic VLAN assignment, where devices can be automatically placed into specific VLANs based on their MAC addresses.

Protocol VLAN

Allows VLAN assignments based on the protocol type in the frame, such as IP or ARP. It enables grouping traffic from certain protocols into specific VLANs for easier network management.

VLAN Port Settings

VLAN Port Members

On this page, the user can define both Tagged and Untagged VLANs (members) for each port individually.

Voice VLAN

A voice VLAN (virtual local area network) is a dedicated VLAN specifically designed to carry voice traffic, such as IP phone calls. By isolating voice traffic from other types of network traffic, voice VLANs help ensure that voice calls are prioritized and experience minimal latency or jitter. This is critical to maintaining clear and uninterrupted voice communications.

Voice VLAN advantages:

  • Improved voice quality: By isolating voice traffic from other types of network traffic, voice VLANs help reduce the latency and jitter that can cause choppy or distorted audio during voice calls.
  • Reduced congestion: By prioritizing voice traffic, voice VLANs help prevent other types of network traffic from interfering with voice calls, even during periods of heavy network usage.
  • Simplified network management: Voice VLANs can simplify network management by making it easier to troubleshoot and resolve voice-related issues.

For example, when an IP phone is connected to a GWN7820 switch port, the switch prioritizes traffic in the voice VLAN, ensuring that voice packets are forwarded before other types of packets.

The user can select more than one way to set up the voice VLAN:

  • Auto Voice VLAN using LLDP
  • Tagged OUI using LLDP
  • Tagged OUI using VLAN Tag
  • Untagged OUI

For more details, please visit this guide: GWN78xx(P) – Voice VLAN Guide.

To configure Voice VLAN, please navigate to Web UI → Switching → VLAN page → Voice VLAN tab.

OUI

An OUI address is a unique identifier assigned by IEEE (Institute of Electrical and Electronics Engineers) to a device vendor. It comprises the first 24 bits of a MAC address. You can recognize which vendor a device belongs to according to the OUI address. The following table shows the OUI addresses of several manufacturers. There is also the option to add a custom one based on user needs.

VLAN OUI

MAC VLAN

MAC VLAN is a networking technique where each VLAN is based on the source MAC address of incoming frames. Devices with the same MAC address share a VLAN. This segmentation enables isolated communication between devices within the same VLAN based on MAC addresses.

VLANs are divided according to the source MAC address of the data frame. Through the configured MAC address and VLAN mapping table, when the switch receives an untagged frame, it adds the specified VLAN Tag to the data frame based on the mapping table.

To add a MAC address to VLAN mapping, click on “Add” button then specify the MAC Address, Mask Length, VLAN and the priority (802.1p).

Note:

Only effective for Hybrid port.

VLAN MAC VLAN

Protocol VLAN

VLANs are divided according to the protocol (family) type and encapsulation format to which the data frame belongs. Through the configured protocol domain and VLAN mapping table in the Ethernet frame, when the switch receives an untagged frame, it adds the specified VLAN Tag based on the mapping table.

Note:

Only effective for Hybrid port.

Spanning Tree

STP (Spanning Tree Protocol), Devices running STP discover loops in the network and block ports by exchanging information, in that way, a ring network can be disbranched to form a tree-topological ring-free network to prevent packets from being duplicated and forwarded endlessly in the network.

BPDU (Bridge Protocol Data Unit) is the protocol data that STP, RSTP and MSTP use. Enough information is carried in BPDU to ensure the spanning tree generation. STP is to determine the topology of the network via transferring BPDUs between devices.

This page allows a user to configure and display Spanning Tree Protocol (STP) property configuration including the STP Mode (STP, RSTP or MSTP), Path Cost, Bridge Priority, Max Hops, Hello and Max Aging time and Forward Delay Time.

Spanning Tree Global Settings

Spanning Tree

Set whether to enable Spanning Tree.

Mode

Set the operating mode of Spanning Tree (STP).

  • STP: Standard Spanning Tree Protocol. Provides basic loop prevention but has slow convergence. Use only for compatibility with older or legacy network devices.

  • RSTP: Rapid Spanning Tree Protocol. Faster convergence than STP, suitable for most modern networks. Recommended as the default for typical deployments.

  • MSTP: Multiple Spanning Tree Protocol. Allows grouping of multiple VLANs into a single STP instance. Best suited for large networks with many VLANs that require efficient resource use.

  • PVST+: Per-VLAN Spanning Tree Plus. Runs one STP instance per VLAN, offering detailed control of loop prevention per VLAN. Good for networks with high segmentation.

  • RPVST(+): Rapid Per-VLAN Spanning Tree Plus. Combines the benefits of RSTP and PVST(+), offering fast convergence for each VLAN. Ideal for high-availability environments with VLAN-based traffic control.

Ignore VLAN in BPDU

This feature allows the switch to ignore VLAN-specific information in Bridge Protocol Data Units (BPDUs). This prevents VLAN configurations from influencing Spanning Tree Protocol (STP) decisions across multiple VLANs.

Path Cost

Specify the path cost method (Short, Long, or Legacy). Default is Short.

Bridge Priority

Select the Bridge Priority, In an STP network, the device with the smallest bridge ID is elected as the root bridge.

Default is 32768.

Note: The valid range is 0~61440, which must be a multiple of 4096

Max Hops

Select the Max Hops (the range is 1 – 40). Default is 20

Hello Time (s)

Specify the Hello Time in seconds (the range is 1 -10). Default is 2.

Note: The time interval at which the device running the STP protocol sends the configuration message BPDU , which is used by the device to detect whether the link is faulty.

Max Aging Time (s)

Select The aging time of BPDU packets of the port (the range is 6 – 40). Default is 20.

Forward Delay Time (s)

Specify the Forward Delay Time in seconds (the range is 4 -30). Default is 15.

Enable STP

Set whether to enable STP on this port.

Priority

Priority is an important basis for determining whether the port will be selected as the root port. The port with higher priority under the same conditions will be selected as the root port . The smaller the value , the higher the priority . An integer in the range of 0-240, with a step size of 16, and a default of 128 .

Note: The valid range is 0~240, which must be a multiple of 16

Path Cost

Set the path cost of the port on the specified spanning tree. The default value is 0, which means that path cost calculation is performed automatically.

Note:The valid range of path cost depends on the path cost settings in Global Settings.If set to “Short” in Global Settings, the valid range is 0-65535; if set to “Long”, the valid range is 0-200000000; if set to “legacy”, the valid range is 0-200000.

Edge Port

Set whether to enable Edge Port or disable it, by default it’s on auto.

Notes:

  • A port is considered as an edge port when it is directly connected to the user terminal or server, instead of any other switches or shared network segments. The edge port will not cause a loop upon network topology changes.

  • In the edge mode, the interface would be put into the Forwarding state immediately upon link up. While in auto mode it will detect if the port is an edge or not.

Root Protection

Safeguards the root bridge by preventing designated ports from becoming the root port, thus protecting the current root bridge from being displaced by lower-priority BPDUs.

Loop Protection

Prevents Layer 2 loops by ensuring a blocking state on ports that stop receiving BPDUs, avoiding the formation of network loops.

BPDU Guard

Set whether to enable BPDU Guard.

Note: BPDU Guard further protects your switch by turning this port into error state and shutdown if any BPDU received from this port.

BPDU Filter

Set whether to enable BPDU Filter.

Note: Drop all BPDU packets and no BPDU will be sent.

Point-to-Point

Select Point-to-Point option (Auto, Enabled or Disabled). Default is Auto.

Note: determines the STP of link type for this port automatically if set to Auto.

IP

VLAN IP Interface

Hosts in different VLANs cannot communicate directly and need to be forwarded through routers or layer 3 switching protocols.

A VLAN interface is a virtual interface in Layer 3 mode and is mainly used to implement Layer 3 communication between VLANs, it does not exist on the device as a physical entity. Each VLAN corresponds to an interface by configuring an IP address for it, it can be used as the gateway address of each port in the VLAN so that packets between different VLANs can be forwarded to each other on Layer 3 routing through the VLAN interfaces. GWN switches support IPv4 interfaces as well as IPv6.

IPv4/IPv6 Interface

To add an IP Interface, please click on the “Add” button, refer to the figure below:

Gateway Priority: valid range from 2 [very important] to 255 [least important],

MTU (Maximum Transmission Unit): valid range is 1280-9216.

  • If Static IP is selected: the user can specify the IPv4 or IPv6 manually.
Add VLAN IP Interface

Note:

Gateway Usage Priority:

  • Statically configured gateway (manually set) has the highest priority.
  • Gateway with a specified priority (smaller priority value means higher priority).
  • If priorities are the same, the gateway with the smaller VLAN ID will be used.

IPv6 Router Advertisements

IPv6 Router Advertisements (RAs) are messages sent by routers to provide information to devices on the network, such as the default gateway, DNS servers, and network prefixes. These advertisements help devices configure their IP addresses and routing automatically without the need for manual configuration. In the VLAN IP Interface section, you can configure RAs for each VLAN to manage IPv6 network settings.

IPv6 Router Advertisement

In the Edit IPv6 Router Advertisements screen, you can customize settings for a specific VLAN. This includes enabling or disabling the interface, setting route information, and configuring timeouts and lifetimes for the advertisements. You can also define IPv6 addresses and prefixes, adjust flags for additional configurations, and set the priority of the default route. This allows for fine-tuning the behavior of the advertisements to suit your network requirements.

Edit IPv6 Router Advertisement

MGMT VLAN

When you assign an IP address to the management VLAN interface, the system synchronizes this IP configuration with the corresponding VLAN interface in the device’s Layer 3 IP interface configuration. This ensures that the IP address used for managing the device is consistent with the VLAN’s routing and switching setup.

For example, if you configure the management VLAN with an IP address 192.168.2.100 on VLAN 2, this IP will also be reflected in the IP interface configuration for VLAN 2, ensuring both management and routing functions are aligned.

MGMT VLAN

DHCP Server

When creating a VLAN IP Interface with a static IP, the user can link it with a DHCP Server for hosts to obtain IP addresses.

Please navigate to the Web UI → IP → DHCP Server page.

Step 1: Enable DHCP Server.

Step 2: on Address Pool Settings section, click on “Add” button to add a new address pool.

Note:

  • Global address pool is only used for IP address allocation to DHCP relay.
  • When a VLAN is configured to use DHCP to automatically get an IP address, the system can now prioritize which gateway (the device routing traffic to other networks) to use.

Add a pool range for the DHCP Server, then select the interface (VLAN).

DHCP Add Pool

In this section, the user can configure DHCP Options like the type, Service (for option 43), and option content. It’s also possible to add more DHCP Options by clicking on the “Add” icon as shown below:

DHCP DHCP Server

DHCP Relay

DHCP relay on GWN78xx switch helps a network device pass DHCP messages between clients and servers that are on a completely different networks. When you have a DHCP server that needs to serve clients on different subnets (or VLANs). A DHCP relay agent is a network device that can route between the client’s subnet and the server’s subnet. The relay agent gets the broadcast request from the client and sends it to the server, putting its own interface address as the gateway address (giaddr) field in the packet. This way, the server can tell which subnet the client is on and assign a suitable IP address. The server then sends the reply back to the relay agent, which passes it to the client.

ARP Table

Address Resolution Protocol ARP is a protocol used to resolve IP addresses to MAC addresses. In a local area network, when a host or three-layer network device has data to send to another host or three-layer network device, it needs to know the other party’s network layer address (IP address) because IP addresses must be encapsulated into frames to be sent over the physical network, the sender also needs to know the receiver’s actual physical address (MAC address), which requires a mapping from IP to MAC address. ARP implements the resolution of IP addresses into MAC addresses. A host or Layer 3 network device maintains an ARP table to store the relationship between IP addresses and MAC addresses. ARP entries include dynamic ARP entries and static ARP entries.

Dynamic ARP entry: It is automatically generated and maintained by the ARP protocol through ARP packets, can be aged out, can be updated by new ARP packets, and can be overwritten by static ARP entries. When the aging time is reached and the interface is down, the device immediately deletes the dynamic ARP entry in response.

Static ARP entry: A fixed mapping relationship between IP addresses and MAC addresses manually established by the network administrator, which will not be aged out and will not be overwritten by dynamic ARP entries, which can ensure the security of network communication. Static ARP entries can restrict the local device to use only the specified MAC address when communicating with the peer device with the specified IP address, in this case, the attack packet cannot modify the mapping relationship between the IP address and the MAC address in the ARP table of the local device thus the normal communication between the local device and the peer device is protected.

To configure the ARP Table, please navigate to Web UI → IP → ARP Table.

Neighbor Discovery

Neighbor Discovery Protocol (NDP) is an important basic protocol in the IPv6 protocol system it replaces the ARP and ICMP router discovery of IPv4. It defines the use of ICMPv6 packets to achieve address resolution, neighbor unreachability detection, duplicate address detection, router discovery, redirection, ND proxy, and other functions.

IPv6 address auto-configuration and router discovery rely on two kinds of ICMPv6 messages: RS (Router Solicitation) and RA (Router Advertisement). Hosts send RS messages to ask routers on the same link to send RA messages right away. Routers send RA messages to let hosts know they are there and give them information like IPv6 prefixes, hop limit, MTU, and configuration flags.

To configure ND please navigate to Web UI → IP → Neighbor Discovery.

DNS

Domain Name System DNS provides translation services between domain names and IP addresses. GWN78xx Switches act as a DNS client. When users perform certain applications on the device (such as Telnet to a device or host), they can directly use a memorable and meaningful domain name, and resolve the domain name to the correct address through the domain name system.

DNS domain name resolution is divided into static domain name resolution and dynamic domain name resolution which can be used together when parsing domain names. If the static domain name resolution is unsuccessful, then dynamic domain name resolution will be used, since dynamic domain name resolution may take a certain amount of time and requires the cooperation of the domain name server, some commonly used domain names can be put into the static domain name resolution table, which can greatly improve the effect of domain name resolution.

Global Settings

On this page, the user can designate the switch as a DNS client to resolve DNS names to IP addresses through one or more configured DNS servers. It’s enabled by default.

To configure DNS on GWN78xx switches, navigate to Web UI → IP → DNS, then click on the Global Settings tab.

MULTICAST

IP multicast is a technique for one-to-many communication over an IP infrastructure in a network. To avoid the incoming data broadcasting to all GE/LAG ports, multicast is useful to transfer the data/message to specified GE/LAG ports for IGMP snooping or MLD Snooping. When the Switch receives a message “subscribed” by the client, it must decide to transfer the data to specified GE/LAG ports according to the location of the client (subscribed member).

IGMP Snooping

As an IPv4 Layer 2 multicast protocol, IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to these conversations the switch maintains a map of which links need which IP multicast streams. Multicasts may be filtered from the links which do not need them and thus controls which ports receive specific multicast traffic.

IGMP Snooping Global Settings

This page allows the user to enable/disable IGMP Snooping function, select snooping version, and enable/disable snooping report suppression also select the Multicast Forward Mode and what to do with Unknown Multicast Packet.

As an IPv6 Layer 2 multicast protocol, MLD Snooping maintains the outgoing port information of multicast packets by listening to the multicast protocol packets sent between Layer 3 multicast devices and user hosts, so as to manage and control multicast data . Forwarding of packets at the data link layer. When an MLD protocol packet transmitted between a host and an upstream Layer 3 device passes through a Layer 2 device, MLD Snooping analyzes the information carried in the packet, establishes and maintains a Layer 2 multicast forwarding table based on the information, and guides multicast data in the data stream.

MLD Snooping – Edit VLAN

MLD Snooping Router Port

 If the router port is statically configured, the Layer 2 device will also forward the MLD report and leave message to the static router port. If a static member port is configured, the interface will be added as the outgoing interface in the forwarding table. After a Layer 2 multicast forwarding table entry is established on a Layer 2 device, when the Layer 2 device receives a multicast data packet, it searches for the forwarding table according to the VLAN to which the packet belongs and the destination address of the packet (that is, the IPv6 multicast group address). Whether the item has the corresponding “outbound interface information”. If it exists, the packet is sent to all multicast group member ports; if it does not exist, the packet is discarded or broadcast in the VLAN.

ROUTING

Routing is a process in which the router selects the optimal path according to the destination address of the received data packet and forwards it to the next network node leading to the target network, and the last routing node under this path forwards the data to the target host. (Router refers to both a router in the traditional sense and an Ethernet switch running a routing protocol).

GWN78xx support IPv4 and IPv6 static routing.

Note:

Dynamic routing protocols, such as RIP, RIPng, OSPF, OSPFv3, BGP, and Route Policy, are supported only on Layer 3 models, specifically the GWN781x, GWN782x, and GWN783x series.

Routing Table

A routing table is like a map of the network that shows the best routes to each destination. It achieves this by storing information on how to reach different destinations on a network and with this table the router can decide where to forward packets that it receives from other devices.

To get to the Routing Table, please navigate to Web UI → Routing → Routing Table.

You cane enable/disable Routing Forwarding option, which allows the switch to act as a Layer 3 device, enabling it to forward packets between different networks or VLANs based on the routing table entries.

Routing Table

A routing table contains the following information for each entry: Destination IP address, Mask Length, Protocol Type, Priority, Next Hop, outgoing Interface and Flags.

A routing table gets populated over time with dynamic routing protocols like OSPF and RIP or static entries (manually configured by an administrator) or directly connected networks.

Static Routes

The static route is a special route that requires manual configuration by an administrator. Static routes have different purposes in different network environments:

  • When the network structure is relatively simple, the network can work normally only by configuring static routes.
  • In complex network environments, configuring static routes can improve network performance and ensure bandwidth for important applications, however, when the network fails or the topology changes, the static routes are not automatically updated and must be reconfigured manually.

To add a static route, please navigate to the Web UI → Routing → Static Routes page.

Static Routes

Click on “Add” button to add a new static route. then fill in the Destination IP Address with the mask length then select the next hop or the outgoing interface (VLAN) with specifying the priority.

Please refer to the figure below:

OSPF (Open Shortest Path First)

OSPF stands for Open Shortest Path First, it’s a routing protocol and uses a link state routing algorithm, in other words it collects information about the state of each link in the network to build an overall map about the whole network topology. OSPF is an interior gateway protocol (IGP) same as RIP (Routing Information Protocol), it’s a protocol based on distance vector algorithms. OSPF has many advantages over other routing protocols, such as RIP.

Some Advantages of OSPF protocol:

  • OSPF can perform route summarization, which reduces the size of the routing table and improves scalability.
  • OSPF supports IPv4 and IPv6.
  • OSPF can split the network into areas, which are logical groups of routers that share the same link state information. This reduces the amount of routing information that needs to be exchanged and processed by each router.
  • OSPF can use authentication to secure the exchange of routing information between routers.
  • OSPF can deal with variable length subnet masks (VLSM), which allows for more efficient use of IP addresses and network design.

In this example, we will be using two GWN78xx switches directly connected (neighbors) and a router serving as a DHCP server. Please refer to the figure below:

Example Two GWN78xx Switches
Note:

OSPF is supported only on Layer 3 models, specifically the GWN781x, GWN782x, and GWN783x series.

OSPF Global

To start using OSPF, please navigate to Web UI → Routing → OSPF page → Global tab:

Toggle ON OSPF and enter the Router ID (it can be any IPv4 address) then scroll down to the bottom of the page and click the “OK” button, please refer to the figure below:

Note:

If adjacency relationship has been established, OSPF process needs to be rebooted for the router ID to take effect. Caution: this action will invalidate OSPF routing and result in recalculation. Please use with caution.

OSPF Area Settings

The Area Settings tab allows you to configure different OSPF areas. An OSPF area is a logical grouping of routers that exchange OSPF information.

OSPF Area Settings

To edit an Area Settings, click on the “Edit” button.

  • Area ID: The unique identifier for the OSPF area. Area 0.0.0.0 is the backbone area and must be configured in every OSPF network.
  • Area Type: Defines the type of the area. OSPF supports different area types, including:
    • None: A normal OSPF area that supports all OSPF features.
    • Stub Area: This does not allow external routes to be advertised into the area, reducing the size of the routing table.
    • Not-So-Stubby Area (NSSA): Allows limited external routes, typically from an ASBR (Autonomous System Boundary Router) within the area.
  • No Summary: (only for Stub and NSSA) disables the summarization of routes, forcing the router to advertise specific routes rather than aggregated routes. This may be useful in certain network designs where precise routing information is required.

OSPF NBMA Neighbor

In Non-Broadcast Multi-Access (NBMA) networks, OSPF cannot automatically discover neighbors as it does in broadcast networks. Therefore, you must manually configure the neighbors.

  • Neighbor: The IP address of the neighbor OSPF router that you want to manually add.
  • Hello Interval (s): The time interval between sending hello packets to this neighbor.
  • Priority: The priority assigned to the neighbor. This value influences the selection of the Designated Router (DR) and Backup Designated Router (BDR).
  • Interface Address: The local IP address of the interface that will communicate with the neighbor.

OSPFv3

Building upon OSPF, OSPFv3 (Open Shortest Path First Version 3) is specifically designed for IPv6 networks. While it shares many principles with OSPFv2, OSPFv3 introduces enhancements to accommodate IPv6 addressing and security features.

Key differences and advantages of OSPFv3 over OSPFv2:

  • IPv6 Support: OSPFv3 is designed to support IPv6 natively, allowing for seamless integration into modern IPv6 networks.
  • Authentication: OSPFv3 uses IPsec for authentication, providing enhanced security over OSPFv2, which uses built-in authentication methods like MD5.
  • Address Family Separation: OSPFv3 separates the routing logic from the addressing, allowing for easier extension and support for multiple address families.
  • Link-State Advertisements (LSAs): Introduces new LSAs to support IPv6 prefixes efficiently.

In this example, we will use two GWN78xx switches directly connected (neighbors) and a router serving as a DHCP server. Please refer to the figure below:

Example two GWN78xx Switches
Note:

OSPFv3 is supported only on Layer 3 models, specifically the GWN781x, GWN782x, and GWN783x series.

BGP

Border Gateway Protocol (BGP) is a path-vector routing protocol used to exchange routing information between different networks, or Autonomous Systems (AS), across the internet. BGP is known as the protocol that powers the internet because it manages how packets are routed across large-scale, complex networks. It allows organizations to route traffic efficiently and ensures that data reaches its destination by selecting the most appropriate path.

Key Features of BGP:

  • Scalability: BGP is capable of managing vast networks by sharing routing information across different autonomous systems.
  • Policy-based Routing: BGP allows administrators to define policies and rules to control how routing decisions are made.
  • Redundancy: BGP can provide multiple routes to the same destination, ensuring high availability.

BGP operates between routers within an Autonomous System (Internal BGP or IBGP) and between routers across different Autonomous Systems (External BGP or EBGP). BGP routers exchange routing information, which is used to build the routing tables that direct traffic between networks.

Note:

BGP is supported only on Layer 3 models, specifically the GWN781x, GWN782x, and GWN783x series.

BGP – Global Settings

The Global Settings tab in BGP allows you to configure key parameters that control how the BGP process operates on the router. These settings include defining your Autonomous System (AS) Number, Router ID, and preferences for route selection and stability.

In the Global Settings, you can:

  • Set your AS Number (AS ID), which identifies your network in BGP routing.
  • Specify the Router ID, a unique identifier for the BGP router.
  • Configure Local Preference to control route selection within your Autonomous System.
  • Enable Route Dampening to stabilize the routing table by reducing the impact of route flapping.

For further details on how to configure each of these fields, please refer to the figure and table below.

BGP Global Settings

BGP – Address Family Settings

The Address Family Settings tab allows you to configure routing for different address families (IPv4 and IPv6). You can aggregate routes or import routes using various routing protocols (RIP, OSPF, etc.). These configurations determine how the switch handles route advertisements and ensures efficient network communication.

Navigate to Routing → BGP → Address Family Settings. In this tab, users can select between IPv4 Unicast Routing and IPv6 Unicast Routing. You can also configure Route Aggregation and Import Route options to optimize routing policies.

BGP Address Family Settings
BGP Address Family Settings route aggregation
  1. Click on Route Aggregation, then click Add.
  2. Enter the following fields:
    • IPv4 Address / Mask Length: Specify the IPv4 address and subnet mask length for the route to be aggregated. For example, 192.168.1.0/24 where 24 represents the subnet mask.
      • Explanation: Route aggregation allows the BGP router to represent multiple smaller networks as a single larger network to other BGP peers. This reduces the size of routing tables.
    • AS-set: Toggle this option if you want to aggregate the AS numbers from the original routes.
      • Explanation: The AS-set option preserves the Autonomous Systems (AS) numbers from all the aggregated routes. This is helpful when you want to show all the AS paths through which the aggregated routes have passed.
    • Summary-only: Toggle this option to advertise only the summary route (without advertising the more specific routes).
      • Explanation: The Summary-only option ensures that only the aggregate route is advertised to the BGP peers, and the more specific routes are hidden. This helps simplify the routing information shared with other peers.
  3. Click OK to confirm and add the route aggregation.
BGP Address Family Setting import routes

The IPv4 Import Routes section in the Address Family Settings allows you to import static routes, RIP, and OSPF routes into BGP. This is useful when you want to redistribute routes learned from other routing protocols or static routes into the BGP routing process.

Route Policy

The Route Policy section is used to manage and apply filtering rules based on IPv4 and IPv6 Access Lists or Prefix Lists. BGP uses these rules to filter which routes are advertised or received from peers. This is essential for controlling routing behavior and ensuring only specific routes are allowed or denied according to network policies.

Note:

Route Policy is supported only on Layer 3 models, specifically the GWN781x, GWN782x, and GWN783x series.

Based on IPv4 Access List

The IPv4 Access List option allows users to create rules that filter routes by permitting specific routes based on the IPv4 address and mask length. These rules help to control which routes are advertised or received from BGP peers.

Example Configuration:

  • Name: Allow-Routes-OfficeNetwork
  • Match Pattern: Allow (permits the specified routes).
  • IPv4 Address/Mask Length: 192.168.1.0/24

POE

Power Over Ethernet (PoE) refers to supplying power over an Ethernet network, also known as a local area network-based power supply system PoL or Active Ethernet.

Usually, the terminal devices of the access point need to use a DC power supply, but due to insufficient wiring, these devices need unified power management. At this time, the switch interface provides the power supply function, which can solve the above problems and realize the precise control of the port PoE power supply.

Note:

The GWN78xxP models support PoE Mode A.

Global

This page Displays the Power Supply Info like the number of PoE, Total and Remaining PoE Power, etc, and even the Supply Voltage.

PoE Global

Click on button to soft restart the PoE module function.

PoE Remaining power

PoE Remaining power(W): specify the total reserved power of the PoE power supply, the default is 20 W.

PoE Global Settings

Application scenarios:

The device will dynamically allocate power to each interface according to the power consumed by each interface. During the running process of each PD device, its power consumption will continue to change, and the system will periodically calculate the total power required by all currently connected PDs. Whether the upper limit of the available PoE power is exceeded, if it exceeds, the system will automatically power off the PD device on the interface with lower priority to ensure the normal operation of other devices. However, sometimes there will be a sudden surge in power consumption, the remaining available power of the system cannot support this surge in demand, and the system has not yet had time to calculate the total power consumption exceeding the limit, to disconnect the power supply of the interface with lower priority. When the PoE power supply is overloaded, the overload protection will be powered off, and all PD devices will be powered off. Use the PoE power-reserved command to reasonably set the reserved power of the system. In the event of a sudden surge in power demand, the reserved power of the system can support the sudden demand and ensure that the system has time to power off the devices on the interfaces with low priority. method to ensure the stable operation of other equipment.

Interface PoE configuration

Select the switch interface that supports the PoE power supply to be configured. Multiple choices are possible.

Click on the “Edit” button or icon to change the configuration per port including Power Supply Standard, Power Mode, Power Limit Mode, and Power Supply Priority.

QOS

The popularity of the network and the diversification of services have led to a surge in Internet traffic, resulting in network congestion, increased forwarding delay, and even packet loss in severe cases, resulting in reduced service quality or even unavailability. Therefore, to carry out these real-time services on the network, it is necessary to solve the problem of network congestion. The best way is to increase the bandwidth of the network, but considering the cost of operation and maintenance, this is not realistic. The most effective solution is to apply a ” Guaranteed ” policies govern network traffic. QoS technology is developed under this background. QoS is quality of service, and its purpose is to provide end-to-end service quality assurance for various business needs. QoS is a tool for effectively utilizing network resources. It allows different traffic flows to compete for network resources unequally. Voice, video, and important data applications can be prioritized in network equipment.

Port Priority

On this page, the user can enable/disable port priority for each interface (port/LAG), supported modes are (CoS, DSCP, CoS-DSCP, or IP-Precedence).

Please navigate to Web UI → QoS → Port Priority page.

QoS Port Priority

Then the user can click on the “Edit” button for further configuration per Port/LAG.

Edit Port Priority

Displays the selected port GE/LAG.

Trust Mode

Select the QoS operation mode:

  • None: no packet priority is trusted, and the interface default priority is used.

  • CoS: Traffic is mapped to queues based on the CoS Queue Mapping, it can configured in QoS → Priority Mapping → CoS Mappging page.

  • DSCP: All IP traffic is mapped to queues based on the DSCP field in the IP header. If the traffic is not IP traffic, it is mapped to the lowest priority queue.

  • CoS-DSCP: All IP traffic is mapped to queues based on the DSCP field in the IP header. If the traffic is not IP traffic but has VLAN tag, mapped to queues based on the CoS value in the VLAN tag. it can configured in QoS → Priority Mapping → DSCP Mapping page.

  • IP-Precedence: The IP precedence is a 3-bit field in TOS that threats high priority packets as more important than other packets. it can configured in QoS → Priority Mapping → IP Mapping page.

CoS

Set the CoS value of the interface, the value range is an integer from 0 to 7 (7 is the highest priority ), the default is 0.

Remarking CoS

Set whether to enable Remarking CoS function of outgoing packets, which is disabled by default.

Remarking DSCP

Set whether to enable Remarking DSCP function of outgoing packets, and it is disabled by default.

Re-marking IP Precedence

Set whether to enable Remarking IP Precedence function of outgoing packets, and it is disabled by default.

Note : Only one of DSCP and IP Precedence re-marking can be enabled.

QoS Port Priority

Priority Mapping

Priority mapping is used to realize the conversion between the QoS priority carried in the packet and the internal priority of the device ( also known as the local priority, which is the priority used by the device to differentiate the service level of the packet ) so that the device provides the Differentiated QoS service quality. Users can use different QoS priority fields in different networks according to network planning.

Queue Scheduling

When congestion occurs in the network, the device will determine the processing order of forwarding packets according to the specified scheduling policy, so that high-priority packets are preferentially scheduled.

Queue scheduling algorithm: queue scheduling according to the switch interface.

  • Strict priority (SP, Strict Priority) scheduling: The flow with the highest priority is served first, and the flow with the second highest priority is served until there is no flow at that priority. Each interface of the switch supports 8 queues ( queues 0-7 ), queue 7 is the highest priority queue, and queue 0 is the lowest priority queue. Disadvantage: When congestion occurs, if there are packets in the high-priority queue for a long time, the packets in the low-priority queue cannot be scheduled, and data cannot be transmitted.
  • Weighted Round Robin (WRR, Weighted Round Robin) scheduling: each priority queue is allocated a certain bandwidth, and provides services for each priority queue according to the priority from high to low. When the high-priority queue has used up all the allocated bandwidth, it is automatically switched to the next priority queue to serve it.
  • Weighted Fair Queuing (WFQ): Based on ensuring fairness ( bandwidth, delay) as much as possible, priority considerations are added, so that high-priority packets have more opportunities for priority scheduling than low-priority packets. WFQ can automatically classify flows by their “session” information (protocol type, source and destination IP addresses, source, and destination TCP or UDP ports, priority bits in the ToS field, etc.) Place each flow evenly into different queues, thus balancing the latency of the individual flows as a whole. When dequeuing, WFQ allocates the bandwidth that each flow should occupy at the egress according to the flow priority (Precedence) . The smaller the priority value is, the less bandwidth is obtained; otherwise, the more bandwidth is obtained.
  • SP-WRR: the switch schedules packets in the SP scheduling group preferentially, and when the SP scheduling group is empty, schedules the packets in the WRR scheduling group. Queues in the SP scheduling group are scheduled with the SP queue scheduling algorithm. Queues in the WRR scheduling group are scheduled with WRR.
  • SP-WFQ: the switch schedules packets of queues in the WFQ group based on their minimum guaranteed bandwidth settings, then uses SP queuing to schedule the queues in the SP scheduling group, then uses WFQ to schedule the queues in the WFQ scheduling group in a round robin fashion according to their weights.
Queue Scheduling
Queue Scheduling Edit port

Queue Shaping

When the packet sending rate is higher than the receiving rate, or the interface rate of the downstream device is lower than the interface rate of the upstream device, network congestion may occur. If the size of the service traffic sent by users is not limited, the continuous burst of service data from a large number of users will make the network more congested. To make the limited network resources serve users more effectively, it is necessary to restrict the service flow of users.

Queue Shaping

To configure a port, click on the “Edit” icon under the operation column.

Maximum Rate/CIR (Kbps): Configures the maximum rate of shaping. The value must be an integer between 16-1000000 Kbps and must be multiples of 16. By default, it’s the port rate.

Configuration of Maximum Rate

Rate Limit

Interface rate limit can limit the total rate of all packets sent or received on an interface. The interface rate limit also uses the token bucket to control the flow. If an interface rate limit is configured on an interface of the device, all packets sent through this interface must first be processed through the token bucket of the interface rate limiter. If there are enough tokens in the token bucket, the packet can be sent; otherwise, the packet will be discarded or cached.

To configure Rate Limit, please navigate to Web UI → QoS → Rate Limit.

Rate Limit

To configure a port, click on the “Edit” icon under operation column, then set the CIR and CBS for both Ingress and Egress.

CIR (Committed Information Rate): the guaranteed average transmission rate or the minimum guaranteed traffic delivered in the network.

CBS (Committed Burst Size): the average volume of burst traffic that can pass through an interface.

SECURITY

GWN78xx Switches series support many tools and features to enhance the security of the device against misconfiguration or attacks.

Storm Control

Traffic suppression can limit the rate of broadcast, unknown multicast , unknown unicast, known multicast, and known unicast packets by configuring thresholds , preventing broadcast, unknown multicast packets, and unknown unicast packets from generating broadcast storms. Large traffic impact of known multicast packets and known unicast packets.

Storm control can block the traffic of broadcast, unknown multicast and unknown unicast packets by blocking packets or shutting down ports . The device supports storm control for the above three types of packets on the interface according to the packet rate, byte rate, and percentage . During a detection interval, the device monitors the average rate of three types of packets received on the interface and compares it with the configured maximum threshold. When the packet rate is greater than the configured maximum threshold , the device performs storm control on the interface and executes the Configured storm control actions. Storm control actions include blocking packets and shutting down / shutdown interfaces.

  • If packets are blocked, when the average rate of receiving packets on the interface is less than the specified minimum threshold, storm control will release the blocking of the packets on the interface.
  • If the action is to shut down / shutdown the interface, you need to manually run the command to bring up the interface, or enable the interface state to automatically return to UP, it’s also possible to use the Auto Recovery function to bring up the interface automatically.

Port Security

By converting the MAC address learned by the interface into secure MAC addresses ( including secure dynamic MAC address, secure static MAC address and Sticky MAC) , port security prevents illegal users from communicating with the switch through this interface, thereby enhancing the security of the device.

Security MAC addresses are divided into: Secure Dynamic MAC, Secure Static MAC and Sticky MAC.

Secure Dynamic MAC Address

If enabled but the Sticky MAC function is not enabled.

If the device is restarted, the entries will be lost and need to be relearned. 

Secure Static MAC Address

Static MAC address manually configured when port security is enabled.

The entries will not be aged, and will not be lost after a reboot.

Sticky MAC Address

The MAC address converted after the port security is enabled and the Sticky MAC function is enabled at the same time

The entries will not be aged , and the addresses will not be lost after restarting the device.

Maximum MAC Number

Set the maximum number of MAC addresses to be learned by the interface , the value range is an integer from 1 to 256 , and the default is 1 . After the maximum number is reached , if the switch receives a packet whose source MAC address does not exist, regardless of whether the destination MAC address exists, the switch considers that there is an attack by an illegal user, and will protect the interface according to the port protection configuration (Protect, Restrict or Shutdown).

Sticky MAC

When the port security is enabled, the Sticky MAC function can be enabled, by default it’s disabled . When enabled, the interface will convert the learned secure dynamic MAC address into a Sticky MAC. If the maximum number of MAC addresses has been reached, the MAC address in the non-sticky MAC entry learned by the interface will be discarded , and a trap alarm will be reported according to the interface protection mode configuration.

Port Protection

Set the protection action when the number of MAC addresses learned by the interface reaches the maximum number or static MAC address flapping occurs .

There are three modes (Protect, Restrict or Shutdown), the default is Protect.

  • Protect: Only discard the packets whose source MAC address does not exist, and does not report an alarm.

  • Restrict: Discard packets with nonexistent source MAC addresses and report an alarm.

  • Shutdown: The interface state is set to error-down and an alarm is reported.
    Note: By default, an interface will not automatically recover after being shut down, and the interface can only be enabled by the network administrator under the interface. If you want the shut down interface to be restored automatically , you can enable Port Auto Recovery function to automatically restore the interface status to Up.

Port Security

Port Isolation

With the port isolation function, the isolation between ports in the same VLAN can be realized. As long as the user adds the port to the isolation group, the Layer 2 data isolation between the ports in the isolation group can be realized. The port isolation function provides users with a safer and more flexible networking solution.

Note:

Due to software limitations, only one isolation group is currently supported, and the port isolation function is disabled by default, that is, the port is added to the default isolation group . After joining , two-way isolation is performed between ports .

Port Isolation

ACL

Access control list (ACL) is a collection of one or more rules. A rule is a judgment statement that describes the matching conditions of a packet. These conditions can be the source address, destination address, port number, etc. of the packet. ACL is essentially a packet filter, and the rule is the filter element of the filter. The device matches packets based on these rules, filters out specific packets , and allows or organizes the packets to pass through according to the processing policy of the service module that applies the ACL.

Notes:

  • One ACL supports setting multiple rules . When the rule settings (except the rule number ) are identical, it will prompt ” This rule already exists”
  •  If there is no match after all the rules are traversed , the Deny message will be sent directly .

IPv4/IPv6 ACL

To add an IPv4 or IPv6 ACL rule, navigate to Security → ACL → IPv4 tab or IPv6 tab, then click on “Add” button to add an IPv4/IPv6 based ACL rule.

ACL IPv4IPv6

The rules action can be defined in one of the four ways below:

  • Drop: This action denies or blocks traffic that matches the specified ACL rule, which prevents the packet from being forwarded through the network.
  • Allow: This action permits traffic that matches the ACL rule, allowing the packet to pass through and continue to its destination.
  • Shut Down: This action disables the interface or port that the traffic is passing through if the ACL rule is triggered, effectively stopping all traffic on that interface.
  • Redirect to Interface: This action forwards the traffic matching the ACL rule to a different interface than it was originally destined for, often used for traffic monitoring, load balancing, or security purposes.

Rate Limit Settings

The Rate Limit Settings section in ACL (Access Control List) allows users to configure rate limiting for up to 128 groups. Rate limiting helps manage and control the amount of traffic sent or received on the network, preventing congestion and ensuring fair usage. This feature is crucial for maintaining optimal network performance and avoiding overloads.

ACL Rate Limit Settings

The users can configure up to 128 groups, by clicking on the “Edit icon” under the operation column.

  • Click on the “Edit icon” under the Operation column to configure a group.
  • Select the Rate Limit Type to determine if the limit will be by packet or byte.
  • Specify the Burst Packet/Byte, which sets the maximum number of packets or bytes allowed to be sent in a burst.
  • Set the Rate Threshold, which defines the maximum rate of packets or bytes per second.

IP Source Guard

IP source guard is a source IP address filtering technology based on the Layer 2 interface. It can prevent malicious hosts from forging IP addresses of legitimate hosts to impersonate legitimate hosts, and also ensure that unauthorized hosts cannot access by specifying their IP addresses. network or attack the network. IPSG uses the binding table (source IP address, source MAC address, VLAN to which it belongs, and the binding of the inbound interface ) to match and check the IP packets received on the Layer 2 interface. Only the packets matching the binding table are allowed to pass through.

Note:

It’s recommended to enable first DHCP Snooping by navigating to Security → DHCP Snooping.

To enable IP Source Guard, first navigate to the Security → IP Source Guard page, then select the port and click on “Edit” to configure the port.

IP Source Guard

Then, select the Verification Type where either the verification will be based on IP addresses or both IP and MAC addresses. Max Entries limits the number of IP/MAC addresses (e.g. devices) where 0 indicates no limit.

IP Source Guard Edit port

This page displays the dynamic binding (port, IP, MAC, VLAN) generated when DHCP Snooping is enabled on the GWN78xx switches, also the user can add static binding by clicking on the “Add” button as shown below:

Note:

Dynamic entries require enabling DHCP Snooping.

To import or export the list click on the import or export button respectively.

Quaternary Binding Table

The binding requires specifying the port, IP Address and its mask, MAC address and its mask, and the VLAN ID. This information will be used to verify the traffic and make sure all the traffic is generated by legitimate users.

Anti Attack

In the network, there are a large number of malicious attack packets targeting the CPU and various types of packets that need to be normally sent to the CPU. Malicious attack packets targeting the CPU will cause the CPU to be busy processing attack packets for a long time, thereby causing interruption of other services or even system interruption; a large number of normal packets will also lead to high CPU usage and performance degradation, thus affecting the normal business.

In order to protect the CPU and ensure that the CPU can process and respond to normal services, the switch provides a local attack defense function, which is aimed at the packets sent to the CPU. It operates normally to avoid the mutual influence of various services when the device is attacked.

Attack defense is an important network security feature. It analyzes the content and behavior of the packets sent to the CPU for processing, determines whether the packets have attack characteristics, and configures certain preventive measures against the packets with attack characteristics. Defense attacks are mainly divided into malformed packet attack defense, fragmented packet attack defense, and flood attack defense.

Anti Attack

Dynamic ARP Inspection (DAI)

To defend against man-in-the-middle attacks and prevent data of legitimate users from being stolen by the man-in-the-middle, you can enable dynamic ARP inspection. The device compares the source IP, source MAC, interface, and VLAN information corresponding to the ARP packet with the information in the binding table. If the information matches, it means that the user who sent the ARP packet is legitimate, and the user is allowed. If the ARP packet passes, otherwise it is considered an attack and the ARP packet is discarded.

Dynamic ARP inspection can be enabled in the interface view, or VLAN view. When enabled in the interface view, the binding table matching check is performed on all ARP packets received by the interface; when enabled in the VLAN view. Then, the binding table matching check is performed on the ARP packets belonging to the VLAN received by the interface that joins the VLAN.

When the device discards a large number of ARP packets that do not match the binding table, if you want the device to alert the network administrator in the form of an alarm, you can enable the dynamic ARP inspection discarded packet alarm function. When the number of discarded ARP packets exceeds the alarm threshold, the device generates an alarm.

RADIUS

RADIUS is a distributed, client /server information exchange protocol that can protect the network from unauthorized access. It is often used in various network environments that require high security and allow remote users to access it. This protocol defines the UDP-based RADIUS packet format and its transmission mechanism and specifies destination UDP ports 1812 and 1813 as the default authentication and accounting port numbers, respectively.

Radius provides access services through authentication and authorization and collects and records the use of network resources by users through accounting. The main features of RADIUS protocol are client/server mode, secure message exchange mechanism, and good expansibility.

RADIUS
Note:

While RADIUS shared keys can be configured via the Web UI, only the CLI supports input of pre-encrypted password strings (e.g., $6$…) for secure deployment and automation. For CLI usage and formatting guidelines, refer to the GWN78xx CLI User Guide.

TACACS+

TACACS+ (Terminal Access Controller Control System Protocol) is a security protocol with enhanced functions based on the TACACS protocol. This protocol is similar in function to the RADIUS protocol and uses the client/server mode to implement the communication between the NAS and the TACACS+ server.

TACACS+ is a centralized, client /server structure information exchange protocol, which uses TCP protocol for transmission, and the TCP port number is 49. The authentication, authorization, and accounting servers provided by TACACS+ are independent of each other and can be implemented on different servers. It is mainly used for authentication, authorization, and accounting of access users who access the Internet through point-to-point protocol PPP or virtual private dial-up network VPDN and management users who perform operations.

TACACS+ is similar to RADIUS protocol : ( 1 ) both adopt client /server mode in structure; (2) both use shared keys to encrypt the transmitted user information ; ( 3 ) both have better flexibility and expansibility. TACACS+ has more reliable transmission and encryption characteristics and is more suitable for security control.

TACACS+
Note:

While TACACS+ shared keys can be configured via the Web UI, only the CLI supports input of pre-encrypted password strings (e.g., $6$…) for secure deployment and automation. For CLI usage and formatting guidelines, refer to the GWN78xx CLI User Guide.

AAA

Access control is used to control which users can access the network and which network resources can be accessed. AAA is short for Authentication, Authorization, and Accounting, and provides a management framework for configuring access control on NAS ( Network Access Server) devices.

As a management mechanism of network security, AAA provides services in a modular manner:

  • Authentication , confirming the identity of users accessing the network , and judging whether the visitor is a legitimate network user;
  • Authorization , giving different users Different permissions limit the services that the user can use;
  • Billing , record all operations during the user’s use of network services, including the type of service used, start time, data flow, etc., to collect and record the user’s The usage of network resources, and can realize the charging requirements for events and traffic, and also monitor the network.

AAA adopts a client /server structure. The AAA client runs on the access device, usually referred to as a NAS device, and is responsible for verifying user identity and managing user access; the AAA server is a collective name for the authentication server, authorization server, and accounting server. Responsible for centralized management of user information. AAA can be implemented through a variety of protocols. Currently, devices support AAA based on RADIUS or TACACS + protocol. In practical applications, the RADIUS protocol is most commonly used.

Identity Authentication Management

The Identity Authentication Management feature on Grandstream GWN switches provides a robust method for securing network access through 802.1X and MAC-based authentication. It allows administrators to configure and manage user authentication settings, ensuring only authorized devices can connect to the network, thereby enhancing overall network security and control.

The 802.1X protocol is a port-based network access control protocol. Port-based network access control refers to verifying user identities and controlling their access rights at the port level of LAN access devices. The 802.1X protocol is a Layer 2 protocol and does not need to reach Layer 3. It does not require high overall performance of the access device, which can effectively reduce network construction costs. Authentication packets and data packets are separated by logical interfaces to improve security.

Port Mode

To enable 802.1x and MAC authentication, please navigate to Security → Identity Authentication Management, then Toggle on “802.1X Authentication” and “MAC Authentication“, and click on the “OK” button to save.

On this page also, you can specify a user ID format for MAC-based and enable a Guest VLAN. This ensures these devices remain isolated from the main network while still maintaining limited network connectivity through the Guest VLAN. The Guest VLAN ID directs unauthenticated users to a designated network segment, providing controlled and secure access.

Identity Authentication Management Port Mode

To enable it on a port, select port(s) from the list then click on “Edit” button or click on “Edit icon” on the right side under operation column.

Note: a RADIUS server must first be added under Security → RADIUS.

Authentication Method1

Select the authentication method, two options:

  • 802.1X: it will use 802.1x authentication, RADIUS must be first added.

  • MAC Authentication: it will use local MAC Addresses under Security → Identity Authentication Management page → Local User of MAC-based or RADIUS depending on the seleted method.

Method

•  If MAC Authentication is selected, the user can add two methods: Radius and Local.

•  If 802.1x is selected, the user can only select radius.

Note: When Radius is selected, the switch includes the Calling-Station-Id attribute in the Access-Request message, containing the MAC address of the connected device. This allows RADIUS servers to apply identity-based policies and track client devices using their hardware address.

DHCP Snooping

DHCP snooping ensures that DHCP clients obtain IP addresses from legitimate DHCP servers, and records the correspondence between IP addresses and MAC addresses of DHCP clients to prevent DHCP attacks on the network.

In order to ensure the security of network communication services, the DHCP Snooping technology is introduced, and a firewall is established between the DHCP Client and the DHCP Server to defend against various attacks against DHCP in the network.

When the device reboots, the dynamic binding table for the IP source guard is automatically restored.

Note: Associated with the “Entries Fixed for DHCPv6 Snooping” option of DHCPv6 Snooping.

Users can configure fixed entries for DHCP Snooping, ensuring that when the device reboots, the dynamic binding table for IP source guard is automatically restored after a fixed duration defined in seconds. Note that this is linked to the ‘Entries Fixed for DHCPv6 Snooping’ option in DHCPv6 Snooping.

To enable the DHCP Snooping feature on GWN78xx switches, navigate to Security → DHCP Snooping, then enable DHCP Snooping, to make the DHCP snooping enabled on a VLAN, specify the VLANs or a VLAN range for example 5-8 means VLANs from 5 to 8, click “OK” button to save. Please refer to the figure below:

DHCP Snooping General page

DHCP Snooping Option 82

Option 82 is called the relay agent information option and is inserted by the DHCP relay agent when forwarding client-originated DHCP packets to a DHCP server.

To identify the device accessed by the client, the user specifies the Remote ID, the format can be either Normal (standard) or Private:

  • Normal Format: is generally used when interoperability between different vendors’ equipment is required, for GWN78xx switches by default the MAC Address of the switch will be used, but any other characters in the range of 1-63 can be used.
  • Private Format: is specific to the vendor’s ecosystem and may not be compatible with other vendors’ equipment (check the vendor-specific format).

Option 82 is used to identify both the Circuit ID and Remote ID of the specific port, this can be used to identify the VLAN, interface, and other information where the client is located. To define this information, go to DHCP Snooping → Option 82, choose a specific port:

DHCP Snooping Option 82

Then, select a port, VLAN and Format, and specify the Circuit ID and Remote ID:

DHCP Snooping Option 82 Add Circuit
Note

Please note that the Remote ID per port is different from the global remote ID of the switch.

DHCP Snooping Port Settings

On this page, the user can configure the trusted port(s) that will allow DHCP messages, all other ports that are not trusted will discard the DHCP messages, this way GWN78xx will protect users from rogue DHCP servers that are plugged into untrusted ports.

To configure a port(s), either select the port(s) and click on the “Edit” button or click on the “Edit icon” under the operation column as seen below:

DHCP Snooping Port Settings

To make a port trusted, Toggle ON Trust Mode, more security parameters can be enabled too like Chaddr Verification, Rate (pps = packet per seconds) to limit the number of DHCP packets, and enable Option 82 for this port with three modes (keep, drop, replace). Please refer to the figure below:

DHCPv6 Snooping Option 18

On this page, the user can configure the Remote ID (Option 37), by default GWN78xx switches use the GWN78xx switches MAC Address.

The DHCPv6 Relay-Option, encompassing Option 18 and Option 37, enables a DHCPv6 relay agent to embed circuit-specific and remote information as a TLV (type-length-value) within the relay message sent to the DHCPv6 server. In this scenario, the managed device functions as a DHCPv6 relay agent.

To add option 18 for a port, click on the “Add” button as shown below:

Upgrade

GWN78xx Switches support manual upload firmware upgrade via a BIN file that can downloaded from Grandstream Firmware page: https://www.grandstream.com/support/firmware.

Upgrading via network is also possible using 5 of these protocols:

  • TFTP
  • HTTP
  • HTTPS
  • FTP
  • Explicit FTPS

Once the protocol is selected, then the user needs to specify the firmware Server Path (For example: firmware.grandstream.com).

Note:

  • Username and Password must be specified if the Server requires it.
  • For FTP protocol use the header “ftp://” and for FTPS use “ftps://
  • Considering the memory problem of the device, the upload upgrade supports streaming upgrade, and the upgrade is carried out while uploading.

Upgrade

Diagnostics

GWN78xx Switches support many diagnostics tools that can help the user troubleshoot the issue and resolve it. These tools include Logs, Ping, Traceroute, Mirroring, Fiber Module, Copper Test, and One-Click Debugging.

Logs

This page lists all the generated Logs with details level and generated time, also an option to export the list is available.

Diagnostics Logs

Adding a Log Server Address to the logs to be sent to is also supported on the GWN78xx Switches.

Log Server Address

Users can Configure the following elements in the logs settings:

  • Minimum log level: This defines the lowest severity of events that will be logged. “Debug” means all messages, including detailed diagnostic information, will be recorded. Other log levels (e.g., Info, Warning, Error) would filter out lower-priority messages.
  • Log Aggregation: This option allows you to merge multiple logs from various sources or components into a centralized location for easier monitoring, analysis, and management.
  • Timeout: This setting defines the time, in seconds, before the logging operation times out. In the example shown, the timeout is set to 60 seconds. The valid range for the timeout is between 15 and 3600 seconds.
Log Diagnostics

Ping

The user in this page can enter the IP Address or Hostname then click “Start“, the results of the ping command will be shown below.

Ping

Ping Watchdog

Ping Watchdog is a feature designed to monitor the connectivity of a device by continuously pinging a specified IP address. If the device becomes unresponsive to pings, then corrective actions can be triggered based on the configuration settings.

Port: Specifies the port on the device that will be monitored or managed by Ping Watchdog.

Enable: Toggles the Ping Watchdog feature on or off for the selected port.

IP Address: The target IP address to which the device will send ping requests.

Packet Sending Interval (s): Defines how frequently (in seconds) ping packets are sent to the specified IP address.

Delay Time (s): This sets a delay before the Ping Watchdog starts monitoring the device after it’s enabled or after a reboot.

Retry Times: Specifies how many failed ping attempts are allowed before the watchdog takes action.

Shutdown Interval (s): how long the switch keeps the port shutdown before bringing it back up after a Ping Watchdog failure.

Ping watchdog

Traceroute

Another tool is Traceroute which shows the number of hops, and GWN78xx Switches enables the user to run Traceroute commands right from the Switches WEB UI.

Traceroute

Mirroring

Mirroring refers to copying the packets from the specified source to the destination port. The specified source is called the mirroring source, the destination port is called the observing port, and the copied packet is called the mirroring packet.

Mirroring can make a copy of the original packet without affecting the normal processing of the original packet by the device, and send it to the monitoring device through the observation port to determine whether the service running on the network is normal.

The GWN78xx switches support two modes of Port Mirroring: SPAN and RSPAN:

  • SPAN (Local): Traffic is mirrored locally within the same switch.
  • RSPAN (Remote): Traffic is mirrored remotely across a network using a Remote VLAN.
SPAN

The traffic mirroring occurs locally within the same switch. SPAN allows you to capture traffic from one or more ports and send a copy of it to another port, typically connected to a network analyzer or monitoring tool.

  • Ingress Mirroring: Captures incoming traffic on the source port(s).
  • Egress Mirroring: Captures outgoing traffic from the source port(s).
  • Source Port: Where the traffic originates (the port being monitored).
  • Tx/Rx Regular Data Messages: defines what type of traffic (transmit, receive, or both) is monitored on the destination switch.
Port Mirroring
RSPAN

RSPAN (Remote Switched Port Analyzer) allows traffic to be mirrored from one switch to another over a network. Unlike SPAN, which is limited to mirroring traffic locally within the same switch, RSPAN uses a Remote VLAN to transport mirrored traffic across multiple switches, enabling centralized monitoring.

Source Switch Role (RSPAN)
  • Ingress Mirroring: This captures incoming traffic on the specified source port(s). It mirrors the packets received by the port before they are processed by the switch, forwarding them to the designated destination for monitoring or analysis.
  • Egress Mirroring: This captures outgoing traffic from the specified source port(s). It mirrors the packets leaving the port after the switch processes them, forwarding these packets to the monitoring destination.
  • Output Port: This is the port on the source switch where the mirrored traffic is sent. In SPAN, it’s usually a local port that connects to the monitoring device, but in RSPAN, this traffic is forwarded across a network using the Remote VLAN to the destination switch.
  • Remote VLAN: This is the VLAN used to transport mirrored traffic between the source switch and the destination switch in an RSPAN configuration. The source switch forwards mirrored traffic to this VLAN, which allows it to be sent across the network to the destination switch for analysis.
Source Switch Role
Destination Switch Role (RSPAN)
  • Source Port: This is the remote VLAN where the mirrored traffic from the source switch arrives. The destination switch receives the mirrored packets via this VLAN and forwards them to the appropriate monitoring port.
  • Monitor Port TX/RX: This defines what type of traffic (transmit, receive, or both) is monitored on the destination switch.
  • Remote VLAN: The VLAN used to receive mirrored traffic from the source switch. It’s the same VLAN that the source switch uses to forward the mirrored traffic over the network to the destination switch.
Destination Switch Role RSPAN

SNMP

Network Management Protocol (SNMP) is an “Internet-standard protocol for managing devices on IP networks”. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more. SNMP is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. An SNMP-managed network consists of three key components:

  •  Managed device
  • Agent – software which runs on managed devices
  • Network management station (NMS) – software which runs on the manager

A managed device is a network node that implements an SNMP interface that allows unidirectional (read-only) or bidirectional (read and write) access to node-specific information. Managed devices exchange node-specific information with the NMSs. Sometimes called network elements, the managed devices can be any type of device, including, but not limited to, routers, access servers, switches, bridges, hubs, IP telephones, IP video cameras, computer hosts, and printers. An agent is a network-management software module that resides on a managed device. An agent has local knowledge of management information and translates that information to or from an SNMP-specific form. A network management station (NMS) executes applications that monitor and control managed devices. NMSs provide the bulk of the processing and memory resources required for network management. One or more NMSs may exist on any managed network.

The global settings page allows the user to enable the SNMP function with the Local Engine ID or add a Remote Engine ID.

Trap Event

a Trap event refers to an alert or notification that is automatically sent by a device or system when a specific event occurs. These events, shown in the SNMP configuration, are various types of conditions that the system is monitoring. When enabled, the device sends a trap to the SNMP manager, notifying it of occurrences like:

  • Authentication failed: When there is an unauthorized login attempt.
  • Port Up/Down: When a network port goes offline or comes online.
  • Cold Start/Warm Start: When the system or device reboots (cold or warm restart).
SNMP Trap Event

RMON

RMON (Remote Monitoring) based on SNMP (Simple Network Management Protocol) architecture, functions to monitor the network. RMON is currently a commonly used network management standard defined by the Internet Engineering Task Force (IETF), which is mainly used to monitor the data traffic across a network segment or even the entire network to enable the network administrator to take protection measures in time to avoid any network malfunction. In addition, RMON MIB records network statistics information on network performance and malfunction periodically, based on which the management station can monitor the network at any time effectively. RMON is helpful for network administrators to manage the large-scale network since it reduces the communication traffic between the management station and the managed agent.

Note:

RMON Statistics

Ethernet statistics function ( corresponding to the statistics group in the RMON MIB): The system collects basic statistics of each network being monitored. The system will continuously count the traffic of a certain network segment and the distribution of various types of packets, the number of error frames of various types, the number of collisions, etc. The number of data packets, the number of broadcast and multicast packets, the number of received bytes, the number of received packets, etc.

RMON Statistics

RMON History

The system will periodically collect statistics on various traffic information, including bandwidth utilization, number of error packets, and total number of packets based on the History ID.

Click on the “Add” button to create a History ID specifying the Port as well.

RMON History

RMON Event

The event group controls the events and prompts from the device and provides all events generated by the RMON Agent. When an event occurs, it can record logs or send Trap to the network management station.

RMON Event

RMON Alarm

The system monitors the specified alarm variable. After pre-defining a set of thresholds and sampling time for the specified alarm, the system will obtain the value of the specified alarm variable according to the defined time period. When the value of the alarm variable is greater than or equal to the upper threshold, an upper alarm event will be triggered. When the value of the alarm variable is less than or equal to the lower threshold, a lower alarm event is triggered.

Passwordless Remote Access

Passwordless Remote Access lets GDMS Networking (or GWN Manager) open the switch Web UI remotely without prompting for the switch’s local username and password. It’s meant to simplify remote support and day-to-day management, especially in environments where access is handled through the management platform rather than by sharing device credentials.

To enable it on the switch, log in to the switch Web UI and go to System → Access Control. Open the Passwordless Remote Access tab, enable the option, then click OK to apply the change.

Passwordless Remote Access

From GDMS Networking, open the Devices page, locate the target switch, and click the Remote Access icon in the Operation column to launch a proxied Web UI session.

GDMS Remote Access

GDMS will begin establishing the remote access session and display a connection page while the proxy is being created.

Accessing GWN device remotely

Once the session is ready, the switch Web UI opens directly through GDMS without asking for the device password.

GWN78xx switch Web UI

Warning: For security, only enable this feature for devices managed under trusted GDMS/GWN Manager accounts, and disable it when you don’t need passwordless access.

Management Platform Settings

The Manager Settings tab allows the users to configure GWN Manager or GWN Router access parameters (Server address and port). It’s also possible to allow DHCP option 43 and if it’s enabled If enabled, the server address assigned by DHCP Option 43 will be preferred.

Access Control Manager Settings
Note:

When GWN Manager wants to take over a managed switch, it can force the takeover by entering the switch current password.

Management ACL of Hardware-based

On a GWN78xx switch, the hardware management Access Control List (ACL) is designed to optimize resource efficiency by filtering traffic directly at the hardware level before it reaches the CPU. This pre-processing step ensures that only traffic matching the defined security rules is forwarded for further handling, effectively reducing unnecessary CPU load and enhancing overall performance. By offloading the initial traffic validation to the switch hardware, the GWN78xx improves both network efficiency and security.

Management ACL of Hardware based
Add a Hardware based ACL Rule

Management ACL of Software-based

On the GWN78xx switch, the software-based Management ACL uses firewall-like rules to control who can access the network and its management features. This means it sets up restrictions to make sure that only authorized users and devices can access important parts of the switch, helping to keep the network secure and well-managed.

Management ACL of Software based

User Management

There are three levels of users, namely administrator, operator and monitor. The administrator authenticates and authorizes users who log in to the switch according to management need where each user has different permissions and passwords.

  1. Administrator
  • Each device has one and only one administrator.
  • The highest privileges can execute any command.
  • The username admin cannot be changed, only the password can be changed.
  • Support adding, and deleting operator and monitor.
  1. Operator
  • Added by an administrator, there can be multiple accounts as Operators.
  • The second highest authority can execute all commands except the administrator’s key operations and important mandatory commands
  • Can’t change the username, only the password.
  • Support adding, and deleting Monitor users.
Note:

All features of admin are allowed except setting management IP address and factory reset.
