Remote management address
The switch always includes an IP address in its LLDP advertisements. This can be either an address
selected by a default process or an address configured for inclusion in advertisements.
Debug logging
You can enable LLDP debug logging to a configured debug destination (Syslog server, a terminal
device, or both) by executing the debug lldp command. Note that the switch's Event Log does
not record usual LLDP update messages.
