Example The following example configures an interface to support a critical data VLAN (100) and to re-authenticate hosts when no RADIUS server is reachable. console(config)#vlan 100 console(config-vlan100)#interface gi1/0/1 console(config-if-Gi1/0/1)#authentication event server dead action reinitialize vlan 100 authentication event server alive action This command configures the actions to take when at least one authentication server is reachable. Use the no form of the command to set the interface configuration to the default. Syntax authentication event server alive action reinitialize no authentication event server alive action reinitialize Default Configuration By default, hosts moved to the critical data VLAN are not moved back to the port PVID when a RADIUS server becomes reachable. Command Mode Interface (Ethernet) Configuration mode User Guidelines When the alive action is configured to reinitialize, the switch triggers 802.1X reauthentication 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. Command History Syntax added in version 6.6 firmware.
