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 (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.
