This example uses the authentication order of RADIUS, then , and finally, local.
An access request is sent to RADIUS server 1. One of two scenarios can occur. If there is no
response from the server, the request is passed to the next RADIUS server with the next
lowest index (RADIUS server 2) and so on, until the last RADIUS server is attempted
(RADIUS server 5). If server 5 does not respond, the request is passed to the
server 1. If there is no response from that server, the request is passed to the next
server with the next lowest index ( server 2) and so on.
If a request is sent to an active RADIUS server and the user name and password are not
recognized, access is denied and passed on to the next authentication option, in this case, the
server. The process continues until the request is either accepted, denied, or each
server is queried. Finally, if the request is denied by the active server, the local
parameters are checked for user name and password verification. This is the last chance for
the access request to be accepted.
