Usage Guidelines
For Layer 2 EtherChannels, you do not have to create a port-channel interface first before assigning a
physical port to a channel group. Instead, you can use the channel-group interface configuration
command. It automatically creates the port-channel interface when the channel group gets its first
physical port. If you create the port-channel interface first, the channel-group-number can be the same
as the port-channel-number, or you can use a new number. If you use a new number, the channel-group
command dynamically creates a new port channel.

You create Layer 3 port channels by using the interface port-channel command followed by the no
switchport interface configuration command. You should manually configure the port-channel logical
interface before putting the interface into the channel group.

Only one port channel in a channel group is allowed.
Caution
When using a port-channel interface as a routed port, do not assign Layer 3 addresses on the physical
ports that are assigned to the channel group.

Caution
Do not assign bridge groups on the physical ports in a channel group used as a Layer 3 port-channel
interface because it creates loops. You must also disable spanning tree.
