Configuring a software exception handling method
By default, an SRPU automatically reboots when instruction error, illegal address error, data overflow,
null pointer, reset, or any other software anomaly occurs. You can also configure the SRPUs to stay in the
error condition without taking any protective action to preserve the error information for identifying the
problem.
Configuring an exception handling method
When you configure an exception handling method, follow these commands:
• If two SRPUs are used, the reboot of the active SRPU causes an active/standby switchover.
• If one SRPU is used, the reboot of the active SRPU causes the entire switch to reboot.
• An LPU always automatically reboots when it detects a software exception.
• The exception handling action affects only the failed card.
To configure a software exception handling method for SRPUs:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a software
exception handling method
for SRPUs.
system-failure { maintain |
reboot }
Optional.
By default, an SRPU reboots when
software exception occurs.
Displaying the exception handling method
Use the display system-failure command to display the exception handling method.
<Sysname> display system-failure
System failure handling method: reboot
