Chapter 3: Configuration

• 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 prod-

ucts that have IP media capabilities however may or may not be associated with a particular end user. Capabilities include all 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, etc.

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 those defined
for the previous Generic Endpoint (Class I) and Media Endpoint (Class II) classes, and 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 Capabilities: LLDP-MED Capabilities describes the neighborhood unit's LLDP-MED capabilities. The possible

capabilities are:

1. LLDP-MED capabilities

2. Network Policy

3. Location Identification

4. Extended Power via MDI - PSE

5. Extended Power via MDI - PD

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.

4. Guest Voice Signaling - for use in network topologies that require a different policy for the guest voice signaling than for the

guest voice media.

5. Softphone Voice - for use by softphone applications on typical data-centric devices, such as PCs or laptops.

6. Videoconferencing - for use by dedicated videoconferencing equipment and other similar appliances supporting real-time

interactive video/audio services.
