Device Type
(Continued)
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.
LLDP-MED

LLDP-MED Capabilities describes the neighbor unit's LLDP-MED capabilities. The
possible capabilities are:
1. LLDP-MED capabilities
2. Network Policy

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 possible
application types are shown below.
1. 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.
2. Voice Signaling - for use in network topologies that require a different policy for the
voice signaling than for the voice media.
3. 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.
