Usage Guidelines
For Layer 2 EtherChannels, you do not have to create a port-channel interface before assigning physical ports
to a channel group. Instead, you can use the
channel-group
interface configuration command, which
automatically creates the port-channel interface when the channel group obtains 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.
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.
Caution
