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.
