www.dell.com | support.dell.com 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 14-4), each bit represents an LLDP-MED capability (Table 14-4). • The possible values of the LLDP-MED Device Type is listed in Table 14-5. The Dell Force10 system is a Network Connectivity device, which is Type 4. When you enable LLDP-MED in FTOS (using the advertise med command), the system begins transmitting this TLV. Figure 14-4.
