Any configuration or attribute changes that you make to the port-channel interface are propagated to all
interfaces within the same channel group as the port channel (for example, configuration changes are
also propagated to the physical interfaces that are not part of the port channel, but are part of the channel
group).
You can create in on mode a usable EtherChannel by connecting two port groups together.
Do not enable Layer 3 addresses on the physical EtherChannel interfaces. Do not assign bridge groups
Caution
