• PoE (MED Power-over-Ethernet)
• Physical location data (see Configuring location data for LLDP-MED devices on page 193)
NOTE:
LLDP-MED operation requires the macphy_config TLV subelement (enabled by default) that is
optional for IEEE 802.1AB LLDP operation. For more information, see the dot3TlvEnable
macphy_config command (Configuring support for port speed and duplex advertisements
(CLI) on page 184).
Network policy advertisements
Network policy advertisements are intended for real-time voice and video applications, and include these TLV
subelements:
• Layer 2 (802.1p) QoS
• Layer 3 DSCP (diffserv code point) QoS
• Voice VLAN ID (VID)
VLAN operating rules
These rules affect advertisements of VLANs in network policy TLVs:
• The VLAN ID TLV subelement applies only to a VLAN configured for voice operation (vlan <vid> voice ).
• If there are multiple voice VLANs configured on a port, LLDP-MED advertises the voice VLAN having the
lowest VID.
• The voice VLAN port membership configured on the switch can be tagged or untagged. However, if the LLDP-
MED endpoint expects a tagged membership when the switch port is configured for untagged, or the reverse,
a configuration mismatch results. (Typically, the endpoint expects the switch port to have a tagged voice VLAN
membership.)
• If a given port does not belong to a voice VLAN, the switch does not advertise the VLAN ID TLV through this
port.
Policy elements
These policy elements may be statically configured on the switch or dynamically imposed during an authenticated
session on the switch using a RADIUS server and 802.1X or MAC authentication. (Web authentication does not
apply to VoIP telephones and other telecommunications devices that are not capable of accessing the switch
through a Web browser.) The QoS and voice VLAN policy elements can be statically configured with the following
CLI commands:
vlan <vid> voice
vlan <vid> {<tagged | untagged> <port-list>}
int <port-list> qos priority <0-7>
vlan <vid> qos dscp <codepoint>
