Configuring A Dynamic Lacp Aggregation Group; Configuring A Description For An Aggregation Group - 3Com 4200G 12-Port Configuration Manual

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...
Enter system view
Configure the system priority
Enter Ethernet port view
Enable LACP on the port
Configure the port priority
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.
