Syntax:
By default, the
show techcommand displays a single output of switch operating and running-configuration data from several internal switch sources, including:
Example:
show tech command shows sample output from the
show techcommand.To specify the data displayed by the
show techcommand, use thecopy show techcommand.
When you enter the show tech command, a summary of switch operational data is sent to your terminal emulator. You can use your terminal emulator's text capture features to save the show tech data to a text file for viewing, printing, or sending to an associate to diagnose a problem.
For example, if your terminal emulator is the Hyperterminal application available with Microsoft® Windows® software, you can copy the show tech output to a file and then use either Microsoft Word or Notepad to display the data. (In this case, Microsoft Word provides the data in an easier-to-read format.)
The following example uses the Microsoft Windows terminal emulator. If you are using a different terminal emulator application, see the documentation provided with the application.
-
In the
Filefield, enter the path and file name in which you want to store theshow techoutput, as shown in Entering a path and filename for saving show tech output. -
From the global configuration context, enter the
show techcommand:HP Switch# show tech
The
show techcommand output is copied into the text file and displayed on the terminal emulator screen. When the command output stops and displays the following, press the Space bar to display and copy more information.-- MORE --
The CLI prompt appears when the command output finishes.
-
Transfer|Capture Text|Stopin HyperTerminal to stop copying data and save the text file.
If you do not stop HyperTerminal from copying command output into the text file, additional unwanted data can be copied from the HyperTerminal screen.
-
To access the file, open it in Microsoft Word, Notepad, or a similar text editor.
Use the copy show tech command to customize the detailed switch information displayed with the show tech command to suit your troubleshooting needs.
