Correct answer & explanation

Verify port-channel interface exists with show running-config

First, verify that the port-channel interface exists. Then check that physical ports are in the same VLAN and have matching configurations. Next, confirm that the channel-group mode is compatible on all ports. After that, inspect LACP or PAgP counters for errors. Finally, check for hardware or cabling issues if all else fails. This systematic approach isolates configuration errors before hardware faults.
