Performing a Master/Standby Switchover

Performing a Master/Standby Switchover

Context

If you want to adjust the roles of member switches in a CSS or restore the roles of member switches after a quick upgrade, you can perform a master/standby switchover to change a standby switch to the new master switch.

Figure 8-31 shows how the roles in both chassis 1 and 2 change after a master/standby switchover is triggered using commands.

  • The original standby switch becomes the master switch, and the original system standby MPU becomes the system master MPU.
  • The original system master MPU becomes a candidate standby MPU, and the original master switch becomes the standby switch.
  • The standby MPU of the original master switch becomes the system standby MPU and synchronizes data with the system master MPU.
NOTE:

Before running a command to perform a master/standby switchover, ensure that the master switch in the CSS has two MPUs.

Procedure

  1. (Optional) Run the display switchover state command to check whether the CSS meets requirements for a switchover.
  2. Run the system-view command to enter the system view.
  3. Run the slave switchover enable command to enable master/standby switchover.

    By default, master/standby switchover is enabled.

  4. Run the slave switchover command to perform a master/standby switchover.
