aggregation group

By default, an aggregation 
group has no description.

Add the port to the aggregation 
group 

port link-aggregation group 
agg-id 

Required 

 

For a static LACP aggregation group or a manual aggregation group, you are recommended not to 

cross cables between the two devices at the two ends of the aggregation group. For example, suppose 

port 1 of the local device is connected to port 2 of the peer device. To avoid cross-connecting cables, do 

not connect port 2 of the local device to port 1 of the peer device. Otherwise, packets may be lost.  

 

A dynamic LACP aggregation group is automatically created by the system based on LACP-enabled 

ports. The adding and removing of ports to/from a dynamic aggregation group are automatically 

accomplished by LACP. 

You need to enable LACP on the ports which you want to participate in dynamic aggregation of the 

system, because, only when LACP is enabled on those ports at both ends, can the two parties reach 

agreement in adding/removing ports to/from dynamic aggregation groups. 

 

You cannot enable LACP on a port which is already in a manual aggregation group. 

 

Follow these steps to configure a dynamic LACP aggregation group:
