Discovering Network Devices

This chapter describes the Industry Standard Discovery Protocol (ISDP)

feature and the Link Layer Discovery Protocol (LLDP) feature, including

LLDP for Media Endpoint Devices (LLDP-MED).
The topics covered in this chapter include:

Device Discovery Overview
Default IDSP and LLDP Values
Configuring ISDP and LLDP (Web)
Configuring ISDP and LLDP (CLI)
Device Discovery Configuration Examples

Device Discovery Overview

The switch software includes two different device discovery protocols: IDSP

and LLDP. These protocols allow the switch to broadcast information about

itself and to learn information about neighboring devices.

What Is ISDP?

The Industry Standard Discovery Protocol (ISDP) is a proprietary Layer 2

network protocol that inter-operates with Cisco devices running the Cisco

Discovery Protocol (CDP). ISDP is used to share information between

neighboring devices. The switch software participates in the CDP protocol

and is able to both discover and be discovered by other CDP-supporting

devices.

What is LLDP?

LLDP is a standardized discovery protocol defined by IEEE 802.1AB. It allows

stations residing on an 802 LAN to advertise major capabilities physical

descriptions, and management information to physically adjacent devices

allowing a network management system (NMS) to access and display this

information.
