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

—
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.
