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.
