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.
