Command Default

An LLDP-MED network policy is not defined.

Parameters
application-type
Configures the primary function of the applications defined by this network policy. The application type can be one of the following:
guest-voice
Limited voice service for guest users and visitors with their own IP telephony handsets or similar devices that support interactive voice services.
guest-voice-signaling
Limited voice service for use in network topologies that require a different policy for guest voice signaling than for guest voice media.
softphone-voice
Softphone voice service for use with multimedia applications that work in association with VoIP technology, enabling phone calls direct from a PC or laptop. Softphones do not usually support multiple VLANs and are typically configured to use an untagged VLAN or a single tagged data-specific VLAN. Note that when a network policy is defined for use with an untagged VLAN, the Layer 2 priority field is ignored and only the DSCP value is relevant.
streaming-video
Applies to broadcast- or multicast-based video content distribution and similar applications that support streaming video services requiring specific network policy treatment. Video applications that rely on TCP without buffering would not be an intended use of this application type.
video-conferencing
Applies to dedicated video conferencing equipment and similar devices that support real-time interactive video/audio services.
video-signaling
For use in network topologies that require a separate policy for video signaling than for video media. Note that this application type should not be advertised if all the same network policies apply as those advertised in the video conferencing policy TLV.
voice
For use by dedicated IP telephony handsets and similar devices that support interactive voice services.
voice-signaling
For use in network topologies that require a different policy for voice signaling than for voice media. Note that this application type should not be advertised if all the same network policies apply as those advertised in the voice policy TLV.
tagged vlan vlan-id
Specifies the tagged VLAN that the specified application type will use.
untagged
Configures the device to use an untagged frame format.
priority-tagged
Configures the device to use priority-tagged frames. In this case, the device uses the default VLAN (PVID) of the ingress port.
priority priority-value
Configures the Layer 2 priority value to be used for the specified application type. Enter 0 to use the default priority. Valid values are 0 through 7.
dscp dscp-value
Configures the Layer 3 differentiated services codepoint priority value to be used for the specified application type. Enter 0 to use the default priority. Valid values are 0 through 63.
ports
Specifies the ports.
ethernet unit/slot/port
Configures the network policy on the specified Ethernet interface.
to unit/slot/port
Configures the network policy on a range of Ethernet interfaces.
Modes

Global configuration mode

Usage Guidelines

An LLDP-MED network policy defines an endpoint VLAN configuration (VLAN type and VLAN ID) and associated Layer 2 and Layer 3 priorities that apply to a specific set of applications on a port.

Note: This feature applies to applications that have specific real-time network policy requirements, such as interactive voice or video services. It is not intended to run on links other than links between network connectivity devices and endpoints, and therefore does not advertise the multitude of network policies that frequently run on an aggregated link.

Note: In any LLDP-MED configuration with a priority of zero, tagged VLANs cannot be configured. In this scenario, by design, the configuration defaults to an untagged state, and the VLAN associated with the ports is used.

You can specify a list of ports, separated by a space, or a range of ports, or you can combine lists and ranges.

The command cannot support LAG virtual interfaces. Attempting to configure them will have no effect.

The no form of the command removes the defined LLDP-MED network policy for an Endpoint.

Examples

The following example defines an LLDP-MED network policy for an endpoint. 

device(config)# lldp med network-policy application voice tagged vlan 99 priority 3 dscp 22 ports ethernet 1/1/1 to 1/1/3
