How Do I Perform a Master/Standby Switchover in a Stack?

How Do I Perform a Master/Standby Switchover in a Stack?

You can manually trigger a master/standby switchover in a stack if the current roles of member switches do not meet your requirement. For example, you can perform a master/standby switchover to change the roles after a restart or restore the original roles after an upgrade.

The following example describes the master/standby switchover on a CE8800, CE7800, CE6800, and CE5800.
<HUAWEI> display switchover state      //Check whether the stack meets switchover requirements.
   Switchover State  :  Ready          //You can perform a master/standby switchover only when the stack is ready for the switchover.
   Switchover Policy :  Board Switchover
   MainBoard         :  1
   SlaveBoard        :  2
<HUAWEI> system-view
[~HUAWEI] slave switchover enable      //Enable the switchover function.
[*HUAWEI] commit
[~HUAWEI] slave switchover             //Perform a master/standby switchover.
Warning: This operation will switch the slave board to the master board. Continue? [Y/N]: y

Before a master/standby switchover is performed in a stack of CE12800, CE12800E, and CE16800 switches, ensure that the master switch has two MPUs installed.
