Chapter 27 Configuring LLDP and LLDP-MED
•
Note LLDP and LLDP-MED cannot operate simultaneously in a network. By default, a network device sends
only LLDP packets until it receives LLDP-MED packets from an endpoint device. The network device
then sends LLDP-MED packets until it receives only LLDP packets.

Location TLV
Provides location information from the switch to the endpoint device. The location TLV can send
this information:
– Civic location information
Provides the civic address information and postal information. Examples of civic location
information are street address, road name, and postal community name information.
– ELIN location information
Provides the location information of a caller. The location is determined by the Emergency
location identifier number (ELIN), which is a phone number that routes an emergency call to
the local public safety answering point (PSAP) and which the PSAP can use to call back the
emergency caller.
