Alan is an IT administrator for an organization. He needs to verify if all the port channels on Nexus 1000V Switch are enabled for LACP. Which command can be used to verify the same?

`show port-channel traffic` displays traffic statistics for port channels, not LACP enablement status.

`show port-profile` on Nexus 1000V shows configurations of port profiles, which are templates, not the live LACP status of port channels.

The `show port-channel summary` command on Cisco Nexus switches displays a brief overview of all configured port channels, including their operational status, the protocol used (like LACP), and member interfaces. This output allows an administrator to quickly ascertain if LACP is enabled and functioning for each port channel.

`show port-channel usage` is not a standard or recognized command to display LACP enablement status for port channels.
