z
When a primary server, authentication/authorization server or accounting server, fails, the device
automatically turns to the secondary server.
z
Once the primary server fails, the primary server turns into the blocked state, and the device turns
to the secondary server. In this case, if the secondary server is available, the device triggers the
primary server quiet timer. After the quiet timer times out, the status of the primary server is active
again and the status of the secondary server remains the same. If the secondary server fails, the
device restores the status of the primary server to active immediately. If the primary server has
resumed, the device turns to use the primary server and stops communicating with the secondary
server. After accounting starts, the communication between the client and the secondary server
remains unchanged.
z
When both the primary server and the secondary server are in the state of blocked, you need to set
the status of the secondary server to active to use the secondary server for authentication.
Otherwise, the switchover will not occur.
z
If one server is in the active state while the other is blocked, the switchover will not take place even
if the active server is not reachable.
