framework.
Within the LLDP-MED Endpoint Device category, the
LLDP-MED scheme is broken into further Endpoint Device
Classes, as defined in the following.
Each LLDP-MED Endpoint Device Class is defined to build
upon the capabilities defined for the previous Endpoint
Device Class. For-example will any LLDP-MED Endpoint
Device claiming compliance as a Media Endpoint (Class II)
also support all aspects of TIA-1057 applicable to Generic
Endpoints (Class I), and any LLDP-MED Endpoint Device
claiming compliance as a Communication Device (Class III)
will also support all aspects of TIA-1057 applicable to both
Media Endpoints (Class II) and Generic Endpoints (Class I).
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.
