Chapter 5: Configuration
• 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 but 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
devices.
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 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 that support 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 Signalling—for use in network topologies that require a different policy for the voice signalling 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 Signalling—for use in network topologies that require a different policy for the guest voice signalling 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. Video Conferencing—for use by dedicated Video Conferencing equipment and other similar appliances supporting real-time
interactive video/audio services.
7. Streaming Video - for use by broadcast or multicast based video content distribution and other similar applications supporting
streaming video services that require specific network policy treatment. Video applications relying on TCP with buffering
would not be an intended use of this application type.
