Configuration guidelines
When you configure a MAC authentication voice VLAN, follow these restrictions and guidelines:
You can configure only one MAC authentication voice VLAN on a port. The MAC authentication voice VLANs on different ports can be different.
A server-assigned authorization VLAN for a voice terminal takes precedence over the MAC authentication voice VLAN. The port will be assigned to the authorization VLAN if both VLANs coexist. For information about MAC authentication VLAN assignment, see "VLAN assignment."
The MAC authentication voice VLAN feature cannot work with the RADIUS server provided by IMC.
