LLED-MED network policies TLVs
A network policy in the context of LLDP-MED is a VLAN configuration of a device and associated L2 and L3 configurations.
LLDP-MED network policies TLV include:
● VLAN ID
● VLAN tagged or untagged status
● L2 priority
● DSCP value
You can configure a LLDP-MED network policy to generate an individual network policy TLV for each application type. For more
information, see Define network policies.
NOTE:
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 where a connection is made. In this case, configure the signaling application.
