maintain—Maintaining the current status of the failed MPU so that the system does not take any
restoration measures. Some software faults are hard to reproduce, and the printed information will
be lost after the router reboots. In this case, you can maintain the current status of the router,
facilitating fault location.
On a router with two MPUs, rebooting the active MPU triggers an active and standby switchover, and the
former standby MPU takes over.
On a router with only one MPU, rebooting the active MPU reboots the router.
If the FIP or SAP/OAP module encounters software faults, the solving method is always reboot, which
reboots the failed module.
When system faults occur, the system fault solving method applies to only the failed module, and
rebooting the module does not interrupt the other modules.
To solve system faults:
Step Command
Remarks
1.
Enter system view.

N/A
2.
Specify the system fault
solving method for the active
MPU and standby MPU.
system-failure { maintain |
reboot }
Optional
reboot by default for the active
MPU and standby MPU.

Use the display system-failure command to display the system fault solving method.
System failure handling method: reboot
Saving the current configuration of the router
You can save the current configuration of the router in one of the following methods:
•
Fast saving—Executing the save command without the safely keyword. This mode saves the file
more quickly but is likely to lose the existing configuration file if the router reboots or the power fails
during the process. The fast saving mode is suitable for environments where the power supply is
stable.
•
Safe saving—Executing the save command with the safely keyword. The mode saves the file more
slowly but can retain the configuration file in the router even if the router reboots or the power fails
during the process. The safe saving mode is preferred in environments where a stable power supply
is unavailable or remote maintenance is involved.
