interface port-channel
Follow these guidelines when you use the interface port-channel command:
• If you want to use the Cisco Discovery Protocol (CDP), you must configure it only on the physical
port and not on the port-channel interface.
• Do not configure a port that is an active member of an EtherChannel as an IEEE 802.1x port. If
IEEE 802.1x is enabled on a not-yet active port of an EtherChannel, the port does not join the
EtherChannel.
For a complete list of configuration guidelines, see the “Configuring EtherChannels” chapter in the
software configuration guide for this release.
Examples This example shows how to create a port-channel interface with a port channel number of 5:
Switch(config)# interface port-channel 5
You can verify your setting by entering the show running-config privileged EXEC or show
etherchannel channel-group-number detail privileged EXEC command.
