Link Layer Discovery Protocol
From Wikipedia, the free encyclopedia
The Link Layer Discovery Protocol or LLDP is a vendor-neutral Layer 2 protocol that allows a network device to advertise its identity and capabilities on the local network. The protocol was formally ratified as IEEE standard 802.1AB-2005 in May 2005.

Link layer discovery allows a network management system to model the topology of the network by interrogating the MIB databases in the devices.
One of the required fields in LLDP is the VLAN ID.
