Viewing Lldp Information; Viewing Lldp Neighbor Information - HP 7102dl - ProCurve Secure Router Configuration Manual

Viewing LLDP Information

The ProCurve Secure Router automatically runs LLDP with settings suitable
for a typical network. Before you alter these settings, you should examine the
information that the router is actually sending and receiving.
You should also understand how LLDP works so that you can capitalize on
the information LLDP interfaces collect.
By scanning LLDP information, you can determine which devices the router
can reach on the WAN—and whether any unauthorized devices have con-
tacted the local router. You can also discover useful information about neigh-
boring devices such as their capabilities and model numbers. You can also find
the address for the management agents on connecting devices so that you can
configure them remotely (if authorized to do so).

Viewing LLDP Neighbor Information

Each router interface listens for information from devices on the connection
(its neighbor or neighbors). To view information about the router's neighbors,
use this enable mode command:
Syntax: show lldp neighbors [interface <interface ID>] [detail]
A neighbor's LLDP information includes:
chassis ID—MAC address
system name—for example, a router's hostname
port ID or device port—the ID for the neighbor interface that transmitted
this message
TTL—how long, in seconds, this information should be stored
platform—the device model and, for the ProCurve Secure Router, the
Secure Router OS version
