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, and inventory
management.
