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 Dell Networking OS CLI (Advertising 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.
