show port-channel

Displays the link aggregation group (LAG) information for a port-channel.

Syntax

show port-channel [ number | detail | load-balance | summary ]

Parameters

number: Specifies a LAG port-channel group number.
detail: Displays detailed LAG information for a port-channel.
load-balance: Displays the load-balance or frame-distribution scheme among ports in the port-channel.
summary: Displays the summary information per channel-group.

Modes

Privileged EXEC mode

Usage Guidelines

Use this command to display the LAGs present on the system with details about the LACP counters on their member links. LAG interfaces are called port-channels.

If you do not specify a port-channel, all port-channels are displayed.

When using the show port-channel number command, an asterisk in the command output designates that the designated port channel is the primary link through which the BUM (broadcast, unknown unicast and multicast) traffic flows.
