You can display the local LLDP information, neighbor information, statistics,
and status information of a port, where:
• The local LLDP information refers to the TLVs to be advertised by the local
device to neighbors.
• The neighbor information refers to the TLVs received from neighbors.
5. Displaying global LLDP
