MED TLV
LLDP Media Endpoint Discovery (MED) is an extension of LLDP that provides additional
capabilities to support media endpoint devices. MED enables advertisement and discovery
of network policies, device location discovery to allow creation of location databases, and
information for troubleshooting.
Capabilities TLV
This displays the MED capabilities the remote port supports.

- IETF Geopriv Civic Address based Location Configuration Information
•

- (Emergency Location Identifier Number)
Inventory TLV
The majority of IP Phones lack support of management protocols such as SNMP, so LLDP-MED
inventory TLVs are used to provide their inventory information to the Network Connectivity
Devices such as the Switch. The Inventory TLV may contain the following information.

TLV
Extended Power Via MDI Discovery enables detailed power information to be advertised by
Media Endpoints, such as IP phones and Network Connectivity Devices such as the Switch.
•
Po we r Type
- whether it is currently operating from primary power or is on backup power
(backup power may indicate to the Endpoint Device that it should move to a power
conservation mode).
•
Po we r So urc e
- whether or not the Endpoint is currently operating from an external power
source.
•
Po we r Prio rity
- the Endpoint Device’s power priority (which the Network Connectivity
Device may use to prioritize which devices will remain in service during power shortages)
•
Po we r Va lue
- power requirement, in fractions of Watts, in current configuration
