Description

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.

Note:

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.

Options

This command has no options.

Table 1: show system errors Output Fields
Field Name	Field Description
`Top level root causes`	Display of the top level faults with board level faults followed by component level faults.
`Fx`	Fault number F1 to Fn, where F1 is the first fault and n is the last fault generated by the system.
`(module, error-id, board-name, component-name)`	Information about the fault. Component level faults include the component name.
Group	Fault severity level is Fatal, Major, or Minor.
Scope	Affected scope of fault is System, Component, Board, or Link.
Corr-enabled	Correlation with fault is always enabled, Y.
Time	Time in the format yyyy-mm-dd hh:nn:ss.lll TMZ, where nn is minutes, lll is milliseconds, and TMZ is time zone.
Desc	Description of the fault.
Actions	List of errors that caused the fault.
Root-causes	List of faults that caused this error.
Affected	List of faults that correlate to this root cause.
