LLDP-MED Capabilities TLV
The LLDP-MED capabilities TLV communicates the types of TLVs that the endpoint device and the network
connectivity device support. LLDP-MED network connectivity devices must transmit the Network Policies
TLV.
• The value of the LLDP-MED capabilities field in the TLV is a 2–octet bitmap, each bit represents an
LLDP-MED capability (as shown in the following table).
• The possible values of the LLDP-MED device type are shown in the following. The Dell Networking
system is a network connectivity device, which is Type 4.
When you enable LLDP-MED in Dell Networking OS (using the advertise med command), the system
begins transmitting this TLV.
