When an interface is added to a port channel, FTOS recalculates the hash algorithm.
To add a physical interface to a port channel, use these commands in the following sequence in the
INTERFACE mode of a port channel:
To view the port channel’s status and channel members in a tabular format, use the
show interfaces
port-channel brief
command in the EXEC Privilege mode, as shown in the following example.
FTOS#show int port brief
LAG Mode Status Uptime Ports
1 L2L3 up 00:06:03 Gi 13/6 (Up) *
Gi 13/12 (Up)
2 L2L3 up 00:06:03 Gi 13/7 (Up) *
Gi 13/8 (Up)
Gi 13/13 (Up)
Gi 13/14 (Up)

The example below displays the port channel’s mode (L2 for Layer 2 and L3 for Layer 3 and L2L3 for a
Layer 2 port channel assigned to a routed VLAN), the status, and the number of interfaces belonging to the
port channel.
