LLDP (Link-Layer Discovery Protocol)
To standardize device discovery on all ProCurve switches, LLDP will be
implemented while offering limited read-only support for CDP as documented
in this manual. For the latest information on your switch model, consult the
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.
