PortChannel Configuration Verification
You can view specific information about existing PortChannels at any time from EXEC mode. The
following show commands provide further details on existing PortChannels. You can force all screen
output to go to a printer or save it to a file. See Examples
The show port-channel summary command displays a summary of PortChannels within the switch. A
one-line summary of each PortChannel provides the administrative state, the operational state, the
number of attached and active interfaces (up), and the first operational port (FOP), which is the primary
operational interface selected in the PortChannel to carry control-plane traffic (no load-balancing). The
FOP is the first port that comes up in a PortChannel and can change if the port goes down.The FOP is
also identified by an asterisk ( * ).
