Use the no form of the command to disable voice VLAN access in such cases. Syntax authentication event server dead action authorize voice no authentication event server dead action authorize voice Default Configuration Critical voice VLAN is disabled by default. Command Mode Interface Configuration mode (Ethernet) User Guidelines During authentication, the switch identifies a device as a voice device when an Access-Accept is received from the AAA service with Cisco proprietary VSA device-traffic-class=voice. Phones/devices using the voice VLAN are periodically reauthenticated. If no AAA server is available during reauthentication, access to the voice VLAN is removed when authentication fails. Critical voice VLAN supports voice VLAN access on an interface connected to an 802.1X-capable host during RADIUS server outages. Use of this command allows traffic to continue to flow over the voice VLAN when no RADIUS server is available to reauthenticate the IP phone. Newly Layer 2 Switching Commands 900
