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 <strong>Force10</strong> 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.

LLDP-MED Network Policies TLV A network policy in the context of LLDP-MED is a device’s virtual local area network (VLAN) configuration and associated Layer 2 and Layer 3 configurations, specifically: • VLAN ID • VLAN tagged or untagged status • Layer 2 priority • DSCP value The application type is represented by an integer (the Type integer in Table 14-6), which indicates a device function for which a unique network policy is defined. An individual LLDP-MED Network Policy TLV is generated for each application type that you specify with the FTOS command line interface (CLI). Note: With regard to Table 14-6, signaling is a series of control packets that are exchanged between an endpoint device and a network connectivity device to establish and maintain a connection. These signal packets might require a different network policy than the media packets for which a connection is made. In this case, configure the signaling application. Table 14-6. Network Policy Applications Type Application Description 0 Reserved — 1 Voice Specify this application type for dedicated IP telephony handsets and other appliances supporting interactive voice services. 2 Voice Signaling Specify this application type only if voice control packets use a separate network policy than voice data. 3 Guest Voice Specify this application type for a separate limited voice service for guest users with their own IP telephony handsets and other appliances supporting interactive voice services. 4 Guest Voice Signaling Specify this application type only if guest voice control packets use a separate network policy than voice data. 5 Softphone Voice Softphone is a computer program that enables IP telephony on a computer, rather than using a phone. Specify this application type for this type of endpoint device. 6 Video Conferencing Specify this application type for dedicated video conferencing and other similar appliances supporting real-time interactive video. 7 Streaming Video Specify this application type for broadcast or multicast based video content distribution and other similar applications supporting streaming video services. This does not include video applications relying on TCP with buffering. 8 Video Signaling Specify this application type only if video control packets use a separate network policy than video data. 9-255 Reserved — Link Layer Discovery Protocol (LLDP) | 171
