Configuring Port Channels

Verifying the Load-Balancing Outgoing Port ID

Command	Purpose
switch# show port-channel summary	Displays a summary for the port channel interfaces.
switch# show port-channel traffic	Displays the traffic statistics for port channels.
switch# show port-channel usage	Displays the range of used and unused channel
	numbers.
switch# show port-channel database	Displays information on current running of the port
	channel feature.
switch# show port-channel load-balance	Displays information about load-balancing using port
	channels.

Verifying the Load-Balancing Outgoing Port ID

Command Guidelines

The show port-channelload-balancecommand allows you to verify which ports a given frame is hashed to on a port channel. You need to specify the VLAN and the destination MAC in order to get accurate results.

Note Certain traffic flows are not subject to hashing, for example when there is a single port in a port-channel.

To display the load-balancing outgoing port ID, perform one of the tasks listed in the table below.

Command	Purpose
switch# show port-channel load-balance	Displays the outgoing port ID.
forwarding-path interface port-channel
port-channel-idvlan vlan-iddst-ip src-ip dst-mac
src-mac l4-src-port port-idl4-dst-port port-id

Example

This example shows the output of the short port-channelload-balancecommand.

switch# show port-channel load-balance forwarding-path interface port-channel 10 vlan 1 dst-ip 1.225.225.225 src-ip 1.1.10.10 src-mac aa:bb:cc:dd:ee:ff

l4-src-port 0 l4-dst-port 1

Missing params will be substituted by 0's. Load-balance Algorithm on switch: source-dest-port crc8_hash:204 Outgoing port id: Ethernet 1/1 Param(s) used to calculate load balance: dst-port: 0

src-port: 0

dst-ip: 1.225.225.225

src-ip: 1.1.10.10

dst-mac: 0000.0000.0000

src-mac: aabb.ccdd.eeff
