Configuring LLDP, LLDP-MED, and Wired
Location Service
This chapter describes how to configure the Link Layer Discovery Protocol (LLDP), LLDP Media
Endpoint Discovery (LLDP-MED) and wired location service on the Catalyst 3750-X or 3560-X switch.
Unless otherwise noted, the term
switch
refers to a Catalyst 3750-X or 3560-X standalone switch and to
a Catalyst 3750-X switch stack.
Note
For complete syntax and usage information for the commands used in this chapter, see the command

LLDP
The Cisco Discovery Protocol (CDP) is a device discovery protocol that runs over Layer 2 (the data link
layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches). CDP allows
network management applications to automatically discover and learn about other Cisco devices
connected to the network.
To support non-Cisco devices and to allow for interoperability between other devices, the switch
supports the IEEE 802.1AB Link Layer Discovery Protocol (LLDP). LLDP is a neighbor discovery
protocol that is used for network devices to advertise information about themselves to other devices on
the network. This protocol runs over the data-link layer, which allows two systems running different
network layer protocols to learn about each other.
