Usage guidelines
The MAC authentication critical voice VLAN on a port accommodates MAC authentication voice
users that have failed authentication because none of the RADIUS servers in their ISP domain are
reachable.
Before you enable the MAC authentication critical voice VLAN on the port, make sure the following
requirements are met:
•
The port is configured with the voice VLAN.
To configure a voice VLAN on a port, use the
voice-vlan enable
command (see
Layer 2—LAN
Switching Command Reference
).
•
LLDP is enabled both globally and on the port.
The device uses LLDP to identify voice users. For information about LLDP commands, see
Layer 2—LAN Switching Command Reference
.
