LLDP-MED capabilities TLV

The LLDP-MED capabilities TLV communicates the types of TLVs that the endpoint device and the network connectivity device support. The value of the LLDP-MED capabilities field in the TLV is a 2–octet bitmap. Each bit represents an LLDP-MED capability.

LLDP-MED is enabled by default on an interface. If you disable LLDP-MED, use the lldp med enable command to re-enable it on an interface. The device transmits MED PDUs only when it receives a TLV from a peer. The device does not otherwise send PDUs — even if MED is enabled on an interface.
