LLDP-MED capabilities TLV
The LLDP-MED capabilities TLV communicates the types of TLVs that the endpoint device and the network connectivity device
support. The value of the LLDP-MED capabilities field in the TLV is a 2–octet bitmap. Each bit represents an LLDP-MED
capability.
LLDP-MED is enabled by default on an interface. If you disable LLDP-MED, use the lldp med enable command to re-enable
it on an interface. The device transmits MED PDUs only when it receives a TLV from a peer. The device does not otherwise
send PDUs — even if MED is enabled on an interface.

Network policies TLVs
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 use with OS10 commands (see Advertise LLDP-MED TLVs).
