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 ( Figure 26-4 ), each bit
represents an LLDP-MED capability ( Table 26-4 ).
• The possible values of the LLDP-MED Device Type is listed in Table 26-5 . The Dell Force10 system
is a Network Connectivity device, which is Type 4.
When you enable LLDP-MED in FTOS (using the command
advertise med
) the system begins
transmitting this TLV.
