You can configure up to four servers for authentication services on the
Authenticator Configuration page, so you can set up backup authenticators. If you
set up more than one server for the same service, the server first in the list is the
primary server for that service, and the other servers are used in list order when
the previous server times out. If a backup server responds after the primary server
fails, the access point continues to use the backup server for new transactions.

Enter the shared secret used by the server in the Shared Secret entry field. The
c.
shared secret on the bridge must match the shared secret on the server.
Enter the number of seconds the access point should try contacting the
d.
backup server in the Timeout entry field. If this backup server does not
respond within this time, the access point tries to contact the next backup
server on the list. If you don't have another backup server configured, the
access point tries to contact the original primary authentication server.
Select the same authentication methods as those selected on the primary
