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.
Configuring the PAgP Learn Method and Priority
Network devices are classified as PAgP physical learners or aggregate-port learners. A device is a
physical learner if it learns addresses by physical ports and directs transmissions based on that
knowledge. A device is an aggregate-port learner if it learns addresses by aggregate (logical) ports. The
learn method must be configured the same at both ends of the link.
When a device and its partner are both aggregate-port learners, they learn the address on the logical
port-channel. The device sends packets to the source by using any of the ports in the EtherChannel. With
aggregate-port learning, it is not important on which physical port the packet arrives.

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.
