LLDP-MED Network Policies TLV
A network policy in the context of LLDP-MED is a device’s 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 a represented by an integer (the Type integer in Table 29-6, "Network Policy
Applications," in Link Layer Discovery Protocol), 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 CLI (Advertising TLVs).
Note: With regard to Table 29-6, "Network Policy Applications," in Link Layer Discovery Protocol,
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 29-6. 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.
