Network policies TLVs
A network policy in the context of LLDP-MED is a device’s VLAN conguration and associated L2 and L3 congurations.
LLDP-MED network policies TLV include:
• VLAN ID
• VLAN tagged or untagged status
• L2 priority
• DSCP value
An integer represents the application type the Type integer shown in the following table, which indicates a device function where a unique
network policy is dened. An individual LLDP-MED network policy TLV generates for each application type that you use with OS10
commands, see Advertise LLDP-MED TLVs.
NOTE: Signaling is a series of control packets that exchange between an endpoint device and a network-connectivity device to
establish and maintain a connection. These signal packets might require a dierent network policy than the media packets where
a connection is made. In this case, congure the signaling application.

1 — Voice Used for dedicated IP telephony handsets and other appliances supporting interactive voice services.
2 — Voice signaling Used only if voice control packets use a separate network policy than voice data.
3 — Guest voice Used only 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
Used only if guest voice control packets use a separate network policy than voice data.
5 — SoftPhone
voice
Used for softphone application on a device such as a PC or laptop. This class does not support multiple VLANs and
if required, uses an untagged VLAN or a single tagged data-specic VLAN.
6 — Video
conferencing
Used only for dedicated video conferencing and similar appliances supporting real-time interactive video.
7 — Streaming
video
Used for broadcast- or multicast-based video content distribution and similar applications supporting streaming
video services that require specic network policy treatment.
8 — Video signaling Used only if video control packets use a separate network policy than the video data.

Dene network policies
You can manually dene LLDP-MED network policies. LLDP commands that you congure in CONFIGURATION mode are global and aect
all interfaces. LLDP commands you congure in INTERFACE mode aect only the specic interface.
Create a maximum of 32 network policies and attach the LLDP-MED network policies to a port in CONFIGURATION mode.
