Show Tech-Support Command

When contacting Pica8 for technical support, issue the command show tech-support because it captures the complete status of a PicOS switch. It is recommended to send the output of show tech-support command along with the system log. The following samples describe how to obtain the output.

Log in to the switch and enter the cli command at the Linux shell to reach the PicOS L2/L3 operation mode.
