NETGEAR 8800 User Manual Dependency on authentication database order There are four different authentication orders which can be configured per authentication method. These four orders are the following: • RADIUS • Local • RADIUS, Local • Local, RADIUS For each authentication order, the end result is considered in deciding whether to authenticate the client through the authentication failure VLAN or the authentication service unavailable VLAN (if configured). For example, if the authentication order is radius, local, with the RADIUS server unavailable, and local authentication failed, the client is authenticated in the authentication failure VLAN (if one is configured on the port). For local authentication, if the user is not created in the local database, it is considered as service unavailable. If the user is configured but the password does not match, it is considered as an authentication failure. For RADIUS server authentication, if for some reason the user cannot be authenticated due to problems with the RADIUS configuration, the RADIUS server not running, or some other problem then it is considered as an authentication service unavailable. If the actual authentication fails then it is considered as an authentication failure. Configuring Authentication Services Unavailable VLAN When the authentication service is not available for authentication, the supplicant is moved to authentication service unavailable VLAN and given restricted access. To configure the authentication services unavailable VLAN, use the following commands: configure netlogin authentication service-unavailable vlan unconfigure netlogin authentication service-unavailable vlan enable netlogin authentication service-unavailable vlan ports disable netlogin authentication service-unavailable vlan ports If a network login port has web enabled, authentication failure VLAN and authentication service unavailable VLAN configuration are not applicable to MAC and dot1x clients connected to that port. For example, if port 1:2 has network login MAC and web authentication enabled and authentication failure VLAN is configured and enabled on it, and if a MAC client connected to that port fails authentication, it is not moved to authentication failure VLAN.
