show fault-report
This command displays the fault report captured when the XSR experiences a system problem. It
contains information that pinpoints the cause of the software failure. This data is highly technical
and is intended only for the use of service support engineers to diagnose the problem.
The fault report can be viewed in Bootrom monitor mode or on the CLI.
If the XSR experiences a processor exception, the software captures a fault report and restarts
automatically. Only the first fault report is saved in case of multiple failures in a special RAM area
and is preserved if the XSR is re‐booted but is lost if the XSR is powered down.
The fault report contains the following data relevant to the failure:
•
Cause of processor exception
•
Time stamp
•
Contents of processor registers
•
Operating system status
•
Status of tasks, current task (e.g., crashed task)
•
Contents of stacks (task stacks, interrupt stack)
•
Status of one special task (packet processor by default)
•
Code around the crash program counter
•
Task message queues
•
Memory management statistics
•
Task stack traces for all tasks
Watchdog Fault Report
A fault report is also captured in case a catastrophic watchdog interrupt occurs. If the software
does not refresh the watchdog for several seconds a watchdog fault report is captured and the XSR
is warm‐booted. You can then examine the fault report to analyze the problem.
