interface Po1

[jinkazama_2]

When I configure etherchannel, using channel-group 1 for example, the int is references as Po1 ... why is this? what does Po1 stand for?

PO1 is the etherchannel interface - Port channel interface. You can use Po1 interface as Layer 2 or Layer 3 interface incase of L3 you can assign IP to Po1 interface. Po interface represnts the channel, the grouped interfaces...

Please rate me if I helped.

when you use the ChannelGroup command to assign an interface to a etherchannel group, IOS will create the 'Po' interface, if it does not already exist, which is the portChannel interface.

as previously stated this can be used at L2 or L3.

please see the following link for more portChannel info:
