Flow Statistics
For monitoring or even sometimes troubleshooting, the Flow Statistics displays in real time the flow of data with different
units like Octects, Packets, Transmission Rate and OurErrPackets. The option to clear all the statistics or a specific port is
supported as well.
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.
Speed
Set the rate of the interface, the options are {Auto, 10Mbps, 100Mbps, 1000Mbps}.
The default is auto-negotiation.
Note: When set to Auto, the rate of the interface is automatically negotiated between the interface and the peer port
.
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.
Note: Optical ports only support full-duplex mode.
●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.
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.

Flow Statistics
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.
Port Auto Recovery
Link Aggregation
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.
Link Aggregation Group
There are two load balance modes on the GWN780x(P) 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.
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.

Link Aggregation Settings
LACP
LACP or Link Aggregation Control Protocol is based on the priority, and the user can enable a system priority or even specify
the the priority for each port individually.
Link Aggregation – LACP
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
Speed
Set the rate of the interface, the options are {Auto, 10Mbps, 100Mbps, 1000Mbps}.
The default is auto-negotiation.
Note: When set to Auto, the rate of the interface is automatically negotiated between the interface and the peer port
.
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.
System Priority Set the system priority of LACP, the value range is an integer from 1-65535, the default is 32768.
Edit LACP
Port: Select the switch LAG interface to be configured
Port Priority:Set the LACP protocol priority of the port , the value range is an integer from 1 to 65535 , the default
is 1.
Note: The smaller the priority value of the port , the higher the LACP priority of the port.
Timeout: Set the timeout time for receiving LACP packets, the options are { Short, Long} , the default is Short.
●Short mode: the default timeout period for receiving LACP protocol packets is 3 seconds.
●Long mode: the default timeout period for receiving LACP protocol packets is 90 seconds .
