LLDP-MED TLVs
LLDP-MED TLVs provide multiple advanced applications for voice over IP (VoIP), such as basic
configuration, network policy configuration, and address and directory management. LLDP-MED TLVs
satisfy the voice device vendors' requirements for cost effectiveness, ease of deployment, and ease of
management. In addition, LLDP-MED TLVs make deploying voice devices in Ethernet easier.
LLDP-MED TLVs are shown in
