In this video, I show you how to upgrade the software on a Catalyst 9300 switch. This switch is setup in install mode, which is recommended. We verify the MD5 hash of the file, download it via http web server (could also use tftp) to the device, unpackage it, and install it to complete the upgrade.
Stuck? Here is a Cisco document on how it's done as well: https://www.cisco.com/c/en/us/td/docs...
