5.2 LAG
LAG (Link Aggregation Group) is to combine a number of ports together to make a single
high-bandwidth data path, so as to implement the traffic load sharing among the member ports in
the group and to enhance the connection reliability.
For the member ports in an aggregation group, their basic configuration must be the same. The
basic configuration includes STP, QoS, VLAN, port attributes, MAC Address Learning mode
and other associated settings. More details are explained below:
If the ports, which are enabled for the 802.1Q VLAN, STP, QoS and Port Configuration

(Speed and Flow Control), are in a LAG, their configurations would be the same as the
LAG's.
The ports, which are enabled for the half-duplex, Port Security, Port Mirror and MAC

Address Filtering, cannot be added to the LAG.
If the LAG is needed, you are suggested to configure the LAG function here before configuring the
other functions for the member ports.
Tips:
1. Calculate the bandwidth for a LAG: If a LAG consists of the four ports in the speed of 10Gbps
Full Duplex, the whole bandwidth of the LAG is up to 80Gbps (20Gbps * 4) because the
bandwidth of each member port is 20Gbps counting the up-linked speed of 10Gbps and the
down-linked speed of 10Gbps.
2. The traffic load of the LAG will be balanced among the ports according to the Aggregate
Arithmetic. If the connections of one or several ports are broken, the traffic of these ports will
be transmitted on the normal ports, so as to guarantee the connection reliability.
Enable or disable Loopback Detection function for the port.
Select the mode how the switch processes the detected loops.
Alert: When a loop is detected, display an alert.

Port based: When a loop is detected, display an alert and

block the port.
Select the mode how the blocked port recovers to normal status.
Auto: Block status can be automatically removed after

recovery time.
Manual: Block status only can be removed manually.

Displays the port status whether a loopback is detected.
Displays the port status about block or unblock.
Displays the LAG number the port belongs to.
Click the Recover button to manually remove the block status of
selected ports.
