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 manage-
ment. 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.
