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
23456,0050.3e8d.6400
Switch#
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.
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.
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.
Command Purpose
Step 1
Switch(config)# [no] port-channel load-balance
{src-mac | dst-mac | src-dst-mac | src-ip |
dst-ip | src-dst-ip | src-port | dst-port |
src-dst-port}
Configures EtherChannel load balancing.
Use the no keyword to return EtherChannel load
balancing to the default configuration.
