Configuration guidelines
When you configure an 802.1X voice VLAN, follow these guidelines:
You can configure only one 802.1X voice VLAN on a port. The 802.1X voice VLANs on different ports can be different.
To ensure a correct exchange of 802.1X EAPOL packets, you must configure the dot1x eapol untag command. For information about how to configure this command, see "Configuring a port to send EAPOL frames untagged."
A server-assigned authorization VLAN for a voice terminal takes precedence over the 802.1X voice VLAN. The port will be assigned to the authorization VLAN if both VLANs coexist. For information about 802.1 X VLAN manipulations, see "VLAN assignment."
This feature cannot work with the RADIUS server provided by IMC.
