authentication event server dead action This command configures the actions to take when no authentication server is reachable. Use the no form of the command to set the interface configuration to the default. Syntax authentication event server dead action [{reinitialize | authorize}[vlan vlan-id]] no authentication event server dead action • reinitialize-Re-authenticate hosts, potentially into the critical data VLAN. • authorize-Hosts on the data VLAN are switched to the critical data VLAN without re-authentication. • vlan-id-The critical data VLAN identifier. Default Configuration By default, critical data VLAN capability is not enabled. Command Mode Interface (Ethernet) Configuration mode User Guidelines The command configures the critical data VLAN ID. If the VLAN ID is not specified, the port PVID is used as the critical data VLAN ID. The critical data VLAN capability allows hosts to authenticate when no RADIUS server is reachable. This allows potentially limited access to the network via VLAN configuration. The dead-server (all RADIUS servers marked dead) actions are configured per interface using this command. When the dead-server action is configured to reinitialize, the switch triggers 802.1X re-authentication of all authenticated hosts on the port. Hosts on the voice VLAN, unauthenticated VLAN (authentication failed hosts) or guest VLAN are not disturbed. During re-authentication, if all the servers are still dead, the hosts are authenticated successfully into the critical data VLAN. Security Commands 983
