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 IE 3000 switch.

For complete syntax and usage information for the commands used in this chapter, see the command

reference for this release and the "System Management Commands" section in the Cisco IOS

Configuration Fundamentals Command Reference, Release 12.2.

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.

LLDP supports a set of attributes that it uses to discover neighbor devices. These attributes contain type,

length, and value descriptions and are referred to as TLVs. LLDP supported devices can use TLVs to receive

and send information to their neighbors. This protocol can advertise details such as configuration

information, device capabilities, and device identity.
