This command generates tech-support information that is useful for Cisco Technical Support representatives
when troubleshooting a router. By default, the output of this command is saved on the router's hard disk in a
file with .tgz extension. You can share this file with Cisco Technical Support. To share, use the copy command
to copy the .tgz file to a server or local machine. For example, copy harddisk:/showtech/name.tgz
tftp://server_path.
For Cisco Technical Support contact information, see the 'Obtaining Documentation and Submitting a Service
Request' section in the Preface.
