Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands interface port-channel interface port-channel Use the interface port-channel global configuration command to access or create the port-channel logical interface. Use the no form of this command to remove the port-channel. interface port-channel port-channel-number no interface port-channel port-channel-number Syntax Description port-channel-number Port-channel number. The range is 1 to 48. Defaults No port-channel logical interfaces are defined. Command Modes Global configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines For Layer 2 EtherChannels, you do not have to create a port-channel interface first before assigning a physical port to a channel group. Instead, you can use the channel-group interface configuration command. It automatically creates the port-channel interface when the channel group gets its first physical port. If you create the port-channel interface first, the channel-group-number can be the same as the port-channel-number, or you can use a new number. If you use a new number, the channel-group command dynamically creates a new port channel. Only one port channel in a channel group is allowed. 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.
