Configuring EtherChannels
This example shows how to configure an EtherChannel. It assigns two ports to channel 5 with the LACP
mode active:
Switch# configure terminal
Switch(config)# interface range fastethernet1/0/4 -5
Switch(config-if-range)# no ip address
Switch(config-if-range)# no switchport
Switch(config-if-range)# channel-group 5 mode active
Switch(config-if-range)# end
Configuring EtherChannel Load Balancing
This section describes how to configure EtherChannel load balancing by using source-based or
destination-based forwarding methods. For more information, see the
Methods" section on page
Beginning in privileged EXEC mode, follow these steps to configure EtherChannel load balancing. This
procedure is optional.
Command
Step 1
configure terminal
Step 2
port-channel load-balance {dst-ip | dst-mac |
src-dst-ip | src-dst-mac | src-ip | src-mac}
Step 3
end
Step 4
show etherchannel load-balance
Step 5
copy running-config startup-config
To return EtherChannel load balancing to the default configuration, use the no port-channel
load-balance global configuration command.

Purpose
Enter global configuration mode.
Configure an EtherChannel load-balancing method.
The default is src-mac.
Select one of these load-distribution methods:
dst-ip—Load distribution is based on the destination-host IP
•
address.
dst-mac—Load distribution is based on the destination-host
•
MAC address of the incoming packet.
src-dst-ip—Load distribution is based on the
•
source-and-destination host-IP address.
src-dst-mac—Load distribution is based on the
•
source-and-destination host-MAC address.
src-ip—Load distribution is based on the source-host IP
•
address.
src-mac—Load distribution is based on the source-MAC
•
address of the incoming packet.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
