LLDP-MED capabilities TLV
The LLDP-MED capabilities TLV communicates the types of TLVs that the endpoint device and network-connectivity device support. The
value of the LLDP-MED capabilities eld 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
you enable MED on an interface.
