Configuring EtherChannel
To configure the LACP system priority and system ID, perform this task:
This example shows how to configure the LACP system priority:
Switch# configure terminal
Switch(config)# lacp system-priority 23456
Switch(config)# end
Switch(config)#
Switch>show module
Mod Ports Card Type Model Serial No.

This example shows how to verify the configuration:
Switch# show lacp sys-id

The system priority is displayed first, followed by the MAC address of the switch.
Configuring EtherChannel Load Balancing
Note
Load balancing can only be configured globally. As a result, all channels (manually configured, PagP,
or LACP) will use the same load balancing method.
or LACP) will use the same load balancing method.
To configure EtherChannel load balancing, perform this task:
Command
Purpose
Step 1
Router(config)# lacp system-priority
priority_value
(Optional for LACP) Valid values are 1 through 65535.
Higher numbers have lower priority. The default is 32768.
Higher numbers have lower priority. The default is 32768.
Router(config)# no system port-priority
Reverts to the default.
Step 2
Router(config)# end
Exits configuration mode.
Step 3
Router# show lacp sys-id
Verifies the configuration.
