Configuring a MAC authentication voice VLAN
You can configure a MAC authentication voice VLAN on a MAC authentication-enabled port that connects to voice terminals. The MAC authentication voice VLAN feature applies only to voice terminals that support VLAN-tagged packets.
The MAC authentication voice VLAN feature works with a remote authentication server. The device uses the following process to implement this feature:
Identifies a terminal as a voice device from the packet sent by the authentication server when the terminal passes MAC authentication. The authentication server identifies the terminal as a voice device by its OUI information, and then sends the terminal type information to the device.
Assigns the port to the configured voice VLAN as a tagged member and sends the voice VLAN information through an LLDP or CDP packet to the terminal.
