Displaying the current port speed and duplex configuration on a switch port

You can compare port speed and duplex information for a switch port and a connected LLDP-MED endpoint for configuration mismatches by using an SNMP application. You can also use the switch CLI to display this information, if necessary. The show interfaces brief <port-list> and show lldp info remote-device [port-list] commands provide methods for displaying speed and duplex information for switch ports. For information on displaying the currently configured port speed and duplex on an LLDP-MED endpoint, see Viewing the current port speed and duplex configuration on a switch port.
