Support
Network OS creates several files that can help support personnel troubleshoot and diagnose a
problem. This section describes those files and how to access and save the information for support
personnel.
Panic dump, core dump, and FFDC data files
The Network OS creates panic dump files, core files, and FFDC data files when there are problems
in the Network OS kernel. You can view files using the show support command. These files can
build up in the persistent storage and may need to be periodically deleted or downloaded using the
copy support command.
The software watchdog (SWD) process is responsible for monitoring daemons critical to the
function of a healthy switch. The SWD holds a list of critical daemons that ping the SWD periodically
at a predetermined interval defined for each daemon.
If a daemon fails to ping the SWD within the defined interval, or if the daemon terminates
unexpectedly, then the SWD dumps information to the panic dump files, which helps to diagnose
the root cause of the unexpected failure.
Execute the show support command to view these files or the copy support ftp command to send
them to a host workstation using FTP. The panic dump files, core files, and FFDC data files are
intended for support personnel use only.
Trace dumps
The Network OS produces trace dumps when problems are encountered within Network OS
modules. The Network OS trace dump files are intended for support personnel use only. You can
use the copy support command to collect trace dump files to a specified remote location to provide
support when requested.
Using the copy support command
The copy support command is used to send the output of the RASLog messages, the trace files,
and the output of the copy support command to an off-switch storage location through FTP. You can
upload supportsave data from the local switch to an external host or you can save the data on an
attached USB device. The copy support command runs a large number of dump and show
commands to provide a global output of the status of the switch. Refer to the Network OS
Command Reference for more information on the copy support command.
