EtherChannel vs Port-Channel

Can someone tell me what the difference between an EtherChannel vs a Port-Channel?

In the FLG and OCG, sometimes they refer to the bundle as an EtherChannel, and others as Port-Channel.

    etherchannel is the bundle itself of using for example 3 physical ports as 1 logical interface known as a port-channel. so a bit more clarification say you want 2 interfaces fa0/1-0/2 you choose the protocl (lacp or pagp) then you select channel-group 1 in this case it will make a "virtual interface" you can say named port-channel 1. now under this interface it represents fa0/1-0/2 so any changes will be made to these two interfaces.

    It's the same thing. Cisco just likes to be confusing. NX-OS uses "port-channel" exclusively, so it looks they're moving in the right direction.

    I knew port-channel is the logical interface made up of multiple ports, it just confuses me when you do a show etherchannel summary, and it lists all the port-channels you have configured.....why not just make it show port-channel summary?

    Everytime I do copy run start, I always end up staring at the command for like 3 minutes before pressing enter just to make sure I'm backing up the config and not the other way around icon_rolleyes.gif
