Etherchannel config

When configuring an etherchannel one a switch as a layer 2 channel. Does on configure the logical interface using "interface port-channel 1" command?

As a layer 3 channel its necessary to use the command to bind the logical interface to the physical using the "channel-group 1 mode auto" command. Are they configured differently?

Just need help with the difference.

Thanx.

Re: Etherchannel config

Hi Friend,

You don't need to configure "interface port-channel" command for layer 2 etherchannels.

Once you configure "channel-group mode" command under interface configuration mode , interface port-channel will automatically be created with same number which you will used to configure channel-group.
