show tech-support Command
The show tech-support command is useful when collecting a large amount of information about the switch
for troubleshooting purposes. The output of this command can be provided to technical support representatives
when reporting a problem.
The show tech-support command displays the output of several show commands at once. The output from
this command varies depending on your configuration. Use the show tech-support command in EXEC mode
to display general information about the switch when reporting a problem.
You can choose to have detailed information for each command. You can specify the output for a particular
interface, module, or VSAN. Each command output is separated by line and the command precedes the output.
Explicitly set the terminal length command to 0 (zero) to disable auto-scrolling and enable manual
scrolling. Use the show terminal command to view the configured the terminal size. After obtaining the
output of this command, remember to reset your terminal length as required.
Note
You can save the output of this command to a file by appending > (left arrow) and the filename to the show
tech-support command. If you save this file, verify you have sufficient space to do so—each of these files
may take about 1.8 MB. However, you can zip this file using the gzip filename command. Copy the zipped
file to the required location using the copy command and unzip the file using the gunzip command.
The default output of the show tech-support command includes the output of the following commands:
• show switchname
• show system uptime
• show interface mgmt0
