Lldp-Med Endpoint Device Classes; Lldp-Med Operational Support - HP Aruba JL253A Management And Configuration Manual

• Autonegotiate speed and duplex configuration with the switch
• Use the following network policy elements configured on the client port
◦ Voice VLAN ID
◦ 802.1p (Layer 2) QoS
◦ Diffserv codepoint (DSCP) (Layer 3) QoS
• Discover and advertise device location data learned from the switch
• Support ECS (such as E911, 999, and 112)
• Advertise device information for the device data inventory collected by the switch, including:
◦ Hardware revision
◦ Firmware revision
• Provide information on network connectivity capabilities (For example, a multi-port VoIP phone with Layer 2
switch capability)
• Support the fast-start capability
NOTE:
LLDP-MED is intended for use with VoIP endpoints and is not designed to support links between
network infrastructure devices, such as switch-to-switch or switch-to-router links.

LLDP-MED endpoint device classes

LLDP-MED endpoint devices are, by definition, located at the network edge and communicate using the LLDP-
MED framework. Any LLDP-MED endpoint device belongs to one of the following three classes:
• Class 1 (generic endpoint devices): These devices offer the basic LLDP discovery services, network policy
advertisement (VLAN ID, Layer 2/802.1p priority, and Layer 3/DSCP priority), and PoE management. This
class includes such devices as IP call controllers and communication-related servers.
• Class 2 (media endpoint devices): These devices offer all Class 1 features plus media-streaming capability,
and include such devices as voice/media gateways, conference bridges, and media servers.
• Class 3 (communication devices): These devices are typically IP phones or end-user devices that otherwise
support IP media and offer all Class 1 and Class 2 features, plus location identification and emergency 911
capability, Layer 2 switch support, and device information management.

LLDP-MED operational support

The switches offer two configurable TLVs supporting MED-specific capabilities:
• medTlvEnable (for per-port enabling or disabling of LLDP-MED operation)
• medPortLocation (for configuring per-port location or emergency call data)
