A port channel on a switch is a logical connection that consists of one or more physical connections - this is basically what etherchannel is about.

So lets say you have 2 switches and you want to connect them together. But for bandwidth you want to connect them with 2 x 1Gbps ports. If you connect them with 2 separate ports then STP will only utilise one of the links per vlan. So you can "group" the 2 links together to form one link of 2Gbps ie.


gi0/2 are the physical ports

po1 is the logical port channel port that consists of gi0/1 & gi0/2.
