5.8 Link Layer Discovery Protocol (LLDP)
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral Link Layer protocol in the Inter-
net Protocol Suite used by network devices f
or advertising their identity, capabilities, and neigh-
bors on a IEEE 802 LAN. The protocol is formally defined
in IEEE 802.1AB.
