Defining The Radius Configuration - Brocade Communications Systems RFS6000 System Reference Manual

If an external Radius server is configured as the switch's primary user authentication source and
the switch's local Radius Server is defined as an alternate method, the switch first tries to
authenticate users using the external Radius Server. If an external Radius Server is unreachable,
the switch reverts to the local Server's user database to authenticate users. However, if the
external Radius server is reachable but rejects the user or if the user is not found in the external
Server's database, the switch will not revert to the local Radius Server and the authentication
attempt fails.
If the switch's local Radius Server is configured as the primary authentication method and an
external Radius Server is configured as an alternate method, the alternate external Radius Server
will not be used as an authentication source if a user does not exist in the local Server's database,
since the primary method has rejected the authentication attempt.

users accessing the switch managed network. Again, this is recommended as the secondary
means of authenticating users.
