System Configuration and Monitoring Commands

show tech-support
This command generates system and debugging information for the switch and saves it to
a file. You can optionally limit the command output to display only information for a given
protocol or feature.
The command generates a large amount of output, which is saved to a file in compressed
format. The output file name can be specified by outfile option. If the output file already
exists, a new file name is generated with the current time stamp. If the output filename
does not end with ".gz", then ".gz" is appended to the filename. Since output files may be
too large for Flash on the switch we recommend saving files to either an SD card or a USB
storage device whenever possible to avoid switch lockup. This method is not likely to be
appropriate when running the working set option of ATMF across a range of physically
separated switches.
For information on output options, see “Controlling “show” Command Output” on
page 1.37 .
The output of this command may include the result of the following commands:
