To locate the faults, sometimes the manual master/standby switchover is needed. Check whether the master system control board runs normally or the master/standby relationship is coordinative by inspecting the switched system status. The detailed procedures of the manual master/standby operation are described below.

 

 

 

 

 

The master/standby switchover causes the interruption of the

 

 

 

 

 

 

service, so you must backup the system data before

 

 

 

 

 

 

implementing

the

manual

master/standby

switchover.

 

 

 

 

Note

 

 

 

 

 

Otherwise, you may lose the data.

Step 3

 

To

the

master/standby

3P@C(config)#systemswitch.

 

 

 

 

 

 

 

 

 

 

 

 

 

The

master/standby

switchover

 

 

 

 

 

 

 

 

 

 

 

 

 

needs about 20 seconds, and the

 

 

 

 

 

 

 

 

 

 

 

 

 

service is interrupted temporarily in

 

 

 

 

 

 

 

 

 

 

 

 

 

the later 30 seconds. Finally, the

 

 

 

 

 

 

 

 

 

 

 

 

 

standby system control board takes

 

 

 

 

 

 

 

 

 

 

 

 

 

over the service of the master

 

 

 

 

 

 

 

 

 

 

 

 

 

system control board.
