Configuring a Dynamic LACP Aggregation Group 
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: 
To do…  Use the command…  Remarks 
Enter system view 
system-view 
— 
Configure the system priority 
lacp system-priority 
system-priority 
Optional 
By default, the system priority is 
32,768. 
Enter Ethernet port view 
interface interface-type 
interface-number 
— 
Enable LACP on the port 
lacp enable 
Required 
By default, LACP is disabled on a 
port. 
Configure the port priority 
lacp port-priority 
port-priority 
Optional 
By default, the port priority is 
32,768. 
 
 
Changing the system priority may affect the priority relationship between the aggregation peers, and 
thus affect the selected/unselected status of member ports in the dynamic aggregation group. 
 
Configuring a Description for an Aggregation Group 
To do…  Use the command…  Remarks 
Enter system view 
system-view 
—
 
Configure a description for an 
aggregation group 
link-aggregation group agg-id 
description agg-name 
Optional 
By default, no description is 
configured for an aggregation 
group.
