show system errors



Display information about faults in the system. You can display all errors or the errors for one system component. Use this command to understand about faults and their correlation with other events. First, top level root causes are listed, with board level faults followed by component level faults. Next, details for affected faults are listed.

The show output represents five faults, F1 through F5. F4 and F5 are top level faults, where F4 is affected by F1, F2, and F3; and F3 is affected by F1 and F2. The lowest level (leaf) faults, F1, F2, and F5, have no affected events.


For Junos OS Evolved, only the QFX5200 supports this command. For all other Junos OS Evolved platforms, use the show system errors active, show system errors count, show system errors error-id, show system errors fru, or show system errors inactive command.


This command has no options.
