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.

Use the stop-accounting-buffer enable command to enable the device to buffer stop-accounting 

requests getting no responses.  

Use the undo stop-accounting-buffer enable command to disable the device from buffering 

stop-accounting requests getting no responses.  

By default, the device is enabled to buffer stop-accounting requests getting no responses.
