Lldp (Link-Layer Discovery Protocol); Introduction - ProCurve 2626 Management And Configuration Manual

LLDP (Link-Layer Discovery Protocol)

To standardize device discovery on all ProCurve switches, LLDP has been
implemented while offering limited read-only support for CDP as
documented in this manual. For current information on your switch model,
consult the latest Release Notes (available on the ProCurve Networking web
site). If LLDP has not yet been implemented (or if you are running an older
version of software), consult a previous version of the Management and
Configuration Guide for device discovery details.

Displaying Advertisement Data and Statistics
The Link Layer Discovery Protocol (LLDP) provides a standards-based
method for enabling switches to advertise themselves to adjacent devices and
to learn about adjacent LLDP devices.
An SNMP utility can progressively discover LLDP devices in a network by:
1. Reading a given device's Neighbors table (in the Management Information
Base, or MIB) to learn about other, neighboring LLDP devices.
2. Using the information learned in step 1 to find and read the neighbor
devices' Neighbors tables to learn about additional devices, and so on.
