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
