/cx show events [reverse]
The /cx show events command is the same as “/cx show alarms [reverse]”.
See details above.
/cx show AENs [reverse]
The /cx show AENS command is the same as “/cx show alarms [reverse]”.
See details above.
/cx show diag
The /cx show diag command extracts controller diagnostics for technical
support usage. The output contains general information about the controller,
followed by two logs. The first is the diagnostic log and the second is the
controller log. The diagnostic log contains output related to any anomaly or
error in the system, while the controller log is a snapshot of recent controller
activity. The diagnostic log contains persistent and usually less recent data
than the controller log.
Note that some characters might not be printable or rendered correctly (not
readable). You can save the output from this command to a file, where it can
be communicated to technical support or further studied with Linux utilities
such as od(1).
In order to redirect the output you must run the following command from a
command line, not from within the tw_cli shell.
tw_cli /c0 show diag > diag.txt
