LLDP-MED Generic Endpoint (Class I)
The LLDP-MED Generic Endpoint (Class I) definition is applicable to all endpoint
products that require the base LLDP discovery services defined in TIA-1057,
however do not support IP media or act as an end-user communication appliance.
Such devices may include (but are not limited to) IP Communication Controllers,
other communication related servers, or any device requiring basic services as
defined in TIA-1057.

Discovery services defined in this class include LAN configuration, device
location, network policy, power management, and inventory management.

LLDP-MED Media Endpoint (Class II)
The LLDP-MED Media Endpoint (Class II) definition is applicable to all endpoint
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

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 possible 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
