Virtual Connect and HP A-Series switches (A5820) IRF Integration Guide

A5820: LLDP

LLDP (Link-layer Discovery Protocol) is the IEEE standard protocolused by network devices for

advertising their identity, capabilities, and neighbors. LLDP performs functions similar to some other

proprietary protocols, such as Cisco Discovery Protocol(CDP).

LLDP transmits and receives are enabled by default on A5820 interfaces. No configuration is

required.

The “VcD_xyz” string is the unique Virtual Connect domain ID generated internally when creating

Virtual Connect. VC1 and VC2 share the same LLDP “System Name” because they are in the same

Virtual Connect domain. To determine which physical Virtual Connect module is the LLDP neighbor,

use the “Chassid ID” field. This is the Virtual Connect module system MAC address. To determine the

system MAC address for a particular Virtual Connect module, log into Virtual Connect by SSH (Secure

Shell) and use the show interconnect command.
