The data is ex-changed in TLV (Type-Length-Value) format.Both sent and received LLDP-MED data can be monitored at the administrator interface.For a network configuration example that shows LLDP-MED in operation, please refer toSection 5.4, “An LLDP-Med Example”.Displayed Data• Extended Power: Power Consumption; relevant for PoE.• Network policy (voice): VLAN ID and QoS (Quality of Service) parameters for voice trans-port.• Network policy (signalling): VLAN ID and QoS (Quality of Service) parameters for sig-nalling.• LLDP-MED capabilities: The LLDP-MED TLVs supported by the phone and the switch aswell as the specific device class they belong to.• MAC_Phy configuration: Identifies the possible duplex and bit-rate capability of the send-ing device, its current duplex and bit-rate capability, and whether theses settings are theresult of auto-negotiation during the initialization of the link, or of manual set override ac-tions.• System capabilities: The devices advertise their potential and currently enabled func-tions, e. g. "Bridge", "Telephone".• TTL: Time To Live. This parameter determines how long the TLVs are valid. When expired,the device will send a new set of TLVs.> For details on LLDP-MED, please refer to the ANSI/TIA-1057 standard.
