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.

LLDP-MED network policies TLV include:

• VLAN ID

• VLAN tagged or untagged status

• Layer 2 priority

• DSCP value

An integer represents the application type (the Type integer shown in the following table), 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 CLI (XXAdvertising TLVs).

NOTE: As shown in the following table, 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.
