3.23.6 LLDP-MED
When the phone is connected to a switch with LLDP-MED capabilities, it can
receive a VLAN ID and QoS parameters and advertise its own network-related
properties. The data is exchanged in TLV (Type-Length-Value) format.
Both sent and received LLDP-MED data can be monitored at the administrator
interface.
INFO: For details on LLDP-MED, please refer to the ANSI/TIA-
1057 standard.
For a network configuration example that shows LLDP-MED in operation, please
refer to 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 transport.
• Network policy (signalling): VLAN ID and QoS (Quality of Service) param-
eters for signalling.
• LLDEP-MED capabilities: The LLDP-MED TLVs supported by the phone
and the switch as well as the specific device class they belong to.
• MAC_Phy configuration: Identifies the possible duplex and bit rate
capability of the sending device, its current duplex and bit rate capability, and
whether theses settings are the result of auto-negotiation during the initial-
ization of the link, or of manual set override actions.
• System capabilities: The devices advertise their potential and currently
enabled functions, 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.
