LLDP-MED operation requires the macphy_config TLV subelement—enabled
by default—that is optional for IEEE 802.1AB LLDP operation. Refer to the
dot3TlvEnable macphy_config command on page 13-59.
Network Policy Advertisements. Network policy advertisements are
intended for real-time voice and video applications, and include these TLV
subelements:
VLAN Operating Rules. These rules affect advertisements of VLANs in
network policy TLVs:
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:
Layer 2 (802.1p) QoS
Layer 3 DSCP (diffserv code point) QoS
Voice VLAN ID (VID)
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 mem­
bership when the switch port is configured for untagged, or the reverse,
then 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, then the switch does not
advertise the VLAN ID TLV through this port.
vlan < vid > voice
vlan < vid > < tagged | untagged > < port-list >
int < port-list > qos priority < 0 - 7 >
vlan < vid > qos dscp < codepoint >
