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

Marc Jumbo
The maximum Transmission Payload or MTU is typically 1500 bytes, in case the user requires even a bigger MTU length for a specific scenario, there is an option on the GWN7711(P) Switch to enable Jumbo Frame, the maximum Ethernet frame size ranges from 2K up to 15K. The default parameter is 9K.

LAG

• LAG means Link Aggregation Group which groups some physical ports 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.
• To configure LAG, please navigate to Switching → LAG.
• GWN7711(P) switches support up to 4 link aggregation groups as shown in the figure below:
• To edit/configure a LAG, click on the “Edit” icon under the operation column.

Port Habilita	Set whether to enable the interface. it is enabled by default.
Velocitat	Set the rate of the interface, the options are {10Mbps, 100Mbps, 1000Mbps}. The default is 1000Mbps.
Control de flux	Set the flow control on the interface, the options are { Disabled, Enabled}. The default is Enabled. 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.

MAC Address Search
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.

On this page, the user can search using the MAC address and the VLAN, if the device MAC address is found, it will be displayed on the Search Result section.

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 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.

Port VLAN
On this page, the user can select which VLANs (a preset from 1 to 8) can be allowed on GWN7711(P) ports. This is a simplified way to manage VLAN from 1 to 8. To have more flexibility and control, please enable 802.1Q VLAN and Port VLAN will be disabled automatically.

First Enable Port VLAN as shown below:

• When Port VLAN is enabled, 802.1Q VLAN will be automatically disabled and the configured information will be lost.

Click the “Edit” icon under the Operation column to edit a VLAN, then select which ports this VLAN will be allowed on.

VLAN 802.1Q
For more flexibility and control over VLAN configuration, the user can enable 802.1Q VLAN, and this case the user is not only restricted to VLANs from 1 to 8.

Click on the “Add” button to add a VLAN, as shown below:

On this screen, the user can configure the VLAN:

• VLAN: specify the VLAN ID (Range 2-4094).
• Description: enter a description for the VLAN.
• Member Type: a shortcut to untag/tag or remove all members.
• Physical port: select the tagged/untagged ports accordingly.

802.1Q PVID Settings
If the 802.1Q VLAN is enabled, the user can select the PVID (Port VLAN ID) or native VLAN when there is more than one VLAN on a port. Click on the “Edit” icon under operation to modify the PVID on a specific port.

Under PVID, select the VLAN from the drop-down list as shown below:

IGMP SNOOPING

• The GWN7711(P) switches support IGMP snooping, which is an IPv4 Layer 2 multicast protocol that optimizes the handling of multicast traffic in a network by intelligently forwarding traffic only to the ports where interested hosts are located, based on the monitoring of IGMP messages.
• On the Global Settings tab, the users can enable the IGMP Snooping feature by toggling ON the feature, and for Unknown Multicast Packet will be either dropped or flooded as shown below:

IGMP snooping dynamically identifies router ports by monitoring IGMP General Query messages and optimizes the forwarding of multicast traffic to those ports for efficient use of network bandwidth.

• The Dynamic Router Port tab displays all the discovered dynamic router ports, the users can click on the “Refresh” button to refresh the list.

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” Guaranteed ” policies to 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.

QoS Basic Settings
On this page, the user can edit the port priority for each port, supported modes are:

• Port-Based
• 802.1P-Based
• DSCP-Based
• Please navigate to QoS → QoS Basic Settings page:

Select one or multiple ports, then click on the “Edit” button to modify the ports’ priority. The priority range is from 0 to 7, a larger value indicates a higher priority, and value 0 is the default value.

Cartografia prioritària
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.

802.1p Mapping
On this tab, the user can map between 802.1p and CoS (Class of Service) where 0 is the lowest priority and 7 is the highest priority for 802.1p, and by default, CoS is set to be the same (it’s recommended to keep it by default only if necessary or a specific network requires it).

Mapes DSCP
On this tab, the user can map between CoS and DSCP (Differentiated Services Code Point), in this case, 802.1p and CoS mapping must be configured first. (it’s recommended to keep the default settings to keep the consistency between all switches only if it’s necessary or the network requires it)

Nota:
Mapping can be configured based on the specific needs and requirements of the network, and it’s important to ensure consistency across all network devices for effective Quality of Service (QoS) management.

Programació de la cua
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) 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) 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) scheduling: 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.

Select one or multiple ports, then click on the “Edit” button to modify the ports Queuing Algorithm. The default algorithm is set to Strict Priority (SP).

If Weighted Round Robin (WRR) or Weighted Fair Queuing (WFQ) is selected, the Weight option can be configured accordingly, the higher the Weight the higher the traffic priority.

Nota:

• Weighted Round Robin (WRR): Scheduled based on weighted round robin. The weight of each queue is set in packets.
• Weighted Fair Queuing (WFQ): Schedule according to WFQ. The weight of each queue is set by bytes.

Límit de tarifa

• 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 QoS → Rate Limit, then select one or multiple ports, click on the “Edit” button to edit the port(s).

Enable the Ingress (incoming traffic to the switch) and then set the rate limit (in Kbps), and then enable Egress (outgoing traffic) and set the rate limit (in Kbps).

Nota:
CIR is the average rate at which traffic can pass. If both Ingress and Storm Control are enabled, the smaller value between them takes effect.

Control de tempestes
The GWN7711(P) switches support a storm control feature that prevents broadcast, unknown multicast, or unknown unicast by monitoring and limiting excessive traffic on a port. It helps prevent network congestion and performance problems caused by an overwhelming amount of packets. Thresholds are set to limit traffic when defined limits are exceeded.

Navigate to QoS → Storm Control, then select the unit that Storm Control will use:

• Kbps
• pps (packet per second)

Nota:

• When the unit is pps, Ingress enabled at the port may cause errors in the storm control threshold.
• IFG (Inter-Frame Gap) is the duration between the transmissions of two consecutive frames. IFG helps in preventing collisions on the network.

Select one or multiple ports then click on the “Edit” button or icon under column operation to edit the selected port(s). Please refer to the figure and table below:

Unitat	Seleccioneu la unitat:   ●  kbps: Storm control rate will be calculated by octet-based. ●  pps: Storm control rate will be calculated by packet-based.
IFG	Select IFG (Inter Frame Gap):   ●  Exclosos: Exclude IFG when count ingress storm control rate. ●  Inclòs: Include IFG when count ingress storm control rate.

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.

Power Supply Info
