products that have IP media capabilities however may or may not be associated
with a particular end user. Capabilities include all of the capabilities defined for
the previous Generic Endpoint Class (Class I), and are extended to include
aspects related to media streaming. Example product categories expected to
adhere to this class include (but are not limited to) Voice / Media Gateways,
Conference Bridges, Media Servers, and similar.
Discovery services defined in this class include media-type-specific network
layer policy discovery.
LLDP-MED Communication Endpoint (Class III)
The LLDP-MED Communication Endpoint (Class III) definition is applicable to all
endpoint products that act as end user communication appliances supporting IP
media. Capabilities include all of the capabilities defined for the previous Generic
Endpoint (Class I) and Media Endpoint (Class II) classes, and are extended to
include aspects related to end user devices. Example product categories
expected to adhere to this class include (but are not limited to) end user
communication appliances, such as IP Phones, PC-based softphones, or other
communication appliances that directly support the end user.
Discovery services defined in this class include provision of location identifier
(including ECS / E911 information), embedded L2 switch support, inventory
management
 LLDP-MED
Capabilities
LLDP-MED Capabilities describes the neighbor unit's LLDP-MED capabilities.
The possible capabilities are:
1. LLDP-MED capabilities
2. Network Policy
3. Location Identification
4. Extended Power via MDI - PSE
5. Extended Power via MDI - PD
6. Inventory
7. Reserved
 Application Type Application Type indicating the primary function of the application(s) defined for
this network policy, advertised by an Endpoint or Network Connectivity Device.
The poosible application types are shown below.

Voice - for use by dedicated IP Telephony handsets and other similar
appliances supporting interactive voice services. These devices are typically
deployed on a separate VLAN for ease of deployment and enhanced
security by isolation from data applications.

Voice Signaling - for use in network topologies that require a different policy
for the voice signaling than for the voice media.

Guest Voice - to support a separate limited feature-set voice service for
guest users and visitors with their own IP Telephony handsets and other
similar appliances supporting interactive voice services.

Guest Voice Signaling - for use in network topologies that require a
different policy for the guest voice signaling than for the guest voice media.

Softphone Voice - for use by softphone applications on typical data centric
devices, such as PCs or laptops.

Video Conferencing - for use by dedicated Video Conferencing equipment
and other similar appliances supporting real-time interactive video/audio
services.

Streaming Video - for use by broadcast or multicast based video content
distribution and other similar applications supporting streaming video
services that require specific network policy treatment. Video applications
relying on TCP with buffering would not be an intended use of this
application type.

Video Signaling - for use in network topologies that require a separate
policy for the video signaling than for the video media.
 Policy Policy
Unknown
: The network policy for the specified application type is currently
unknown.
Defined
: The network policy is defined.
 TAG TAG is indicating whether the specified application type is using a tagged or an
untagged VLAN. Can be Tagged ot Untagged

Untagged : The device is using an untagged frame format and as such does
not include a tag header as defined by IEEE 802.1Q-2003.

Tagged : The device is using the IEEE 802.1Q tagged frame format
 VLAN ID VLAN ID is the VLAN identifier (VID) for the port as defined in IEEE
802.1Q-2003. A value of 1 through 4094 is used to define a valid VLAN ID. A
value of 0 (Priority Tagged) is used if the device is using priority tagged frames as
defined by IEEE 802.1Q-2003, meaning that only the IEEE 802.1D priority level
is significant and the default PVID of the ingress port is used instead.
