This command configures the actions to take when all the authentication servers are dead. The command also configures the critical VLAN ID. If the VLAN ID is not specified, the port PVID is used as the critical VLAN ID.
Zhe reinitialize action triggers re-authentication for all authenticated clients on the port. Supplicants on the voice VLAN, unauthenticated VLAN (authentication failed clients), and guest VLAN are not disturbed. During re-authentication if all the servers are still dead, the supplicant is authorized and placed in the critical VLAN without contacting the RADIUS server for authentication.
The authorize action authorizes the authenticated supplicants and assigns them to the critical VLAN. Supplicants on the RADIUS assigned VLAN, voice VLAN, unauthenticated VLAN, and guest VLAN are not disturbed. Supplicants authorized on the port PVID are reauthorized on the critical VLAN.
