Configuring Active/Standby Switchover

Configuring Active/Standby Switchover

Context

If the system master MPU becomes faulty, you can perform an active/standby MPU switchover.

After a command is executed to perform an active/standby switchover on a standalone device, the previous standby MPU becomes the new master MPU, and the previous master MPU restarts and then becomes the new standby MPU.

Figure 2-1 shows the role change after an active/standby switchover in a CSS is triggered by commands.
Figure 2-1  Change in roles after a command-triggered active/standby switchover
  • The previous standby switch becomes the new master switch, and the previous system standby MPU becomes the new system master MPU.
  • The previous system master MPU becomes a candidate system standby MPU, and the previous master switch becomes the new standby switch.
  • The standby MPU of the previous master switch becomes the system standby MPU and synchronizes data with the system master MPU.
NOTE:

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

Do not perform an active/standby switchover on a device in any of the following situations:
  • The file system is in use. For example, a file or directory is being created, deleted, or saved.

  • The device is loading or deleting LPU information, which may occur in the following scenarios:
    • LPUs are hot swapped.

    • LPUs are reset using commands.

  • The active and standby MPUs have different memory sizes.

NOTICE:

During an active/standby switchover, do not insert, remove, or reset active and standby MPUs, LPUs, power modules, or fan modules. Otherwise, the device may restart or become faulty.

Procedure

  1. (Optional) Run display switchover state

    The active/standby switchover status is displayed. According to the status, determine whether the active and standby MPUs meet switchover requirements.

  2. Run system-view

    The system view is displayed.

  3. Run slave switchover enable

    Active/standby switchover is enabled.

    By default, the active/standby switchover function is enabled.

  4. (Optional) Run switchover-prohibit enable

    The function of prohibiting an active/standby switchover following a standby MPU fault is enabled.

    By default, the function of prohibiting an active/standby switchover following a standby MPU fault is enabled.

  5. Run slave switchover

    An active/standby switchover is performed.
