neighbor, it stores this information as two separate entries if the

advertisements have differences chassis ID and port ID information. However,

if the chassis and port ID information are the same, the switch stores this

information as a single entry.

LLDP data transmission/collection is enabled in the switch’s default

configuration. In this state, an SNMP network management application

designed to discover devices running LLDP can retrieve neighbor information

from the switch.

Configuring LLDP Operation

In the default configuration, LLDP is enabled and in both transmit and receive

mode on all active ports. The LLDP configuration includes global settings that

apply to all active ports on the switch, and per-port settings that affect only

the operation of the specified ports.

The commands in this section affect both LLDP and LLDP-MED operation. for

information on operation and configuration unique to LLDP-MED, refer to
