LLDP-MED
The IEEE 802.1AB standard, Link Layer Discovery Protocol (LLDP), describes a
method by which stations residing on a LAN advertise identification information,
capabilities, and physical descriptions. The information is exchanged in LLDP data
units (LLDPDUs) which comprise type-length-value (TLV) structures. Various TLVs
might be included in LLDPDUs, depending on the information that the
administrator configures the port to advertise.
Information learned through LLDPDUs is stored in MIBs, and the information might
be accessible by a network management system (NMS) such as SNMP. This
framework is extensible and allows advanced utilization in areas such as VoIP
networks.
NOTE
LLDPDUs only communicate information; they do not automatically configure the
switch.
The switch supports the LLDP Media Endpoint Discovery (LLDP-MED) extensions
to the LLDP protocol. LLDP-MED enables auto-discovery of LAN policies, device
location, and other device characteristics, and automates management of Power-
over-Ethernet (PoE) endpoints.
