IOS 17.9.5

[godtakuva28]

I am a system admin at a school district. I recently upgraded our Cisco 9300-48UXM firmware from 17.6.5 to 17.9.5 boy what a mistake! I lost my remote access. I had to go to the site to console in. My network admin helped me with getting the network up. We erased and configured from scratch then it worked. Spanning tree was messed up. Also device tracking policy caused problems. Are there other people recently installed 17.9.5 and how was your experience?

 What was the error message you found in console?

   - Always check the release notes for a target version before proceeding , sometimes you need to upgrade ROMMON first:
      https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9300/software/release/17-9/release_notes/ol-17-9-9300/rommon_versions.html?bookSearch=true

    + Remember to always save the running configuration to startup config (too)

We dumped 17.9.4/4a and 17.9.5 for 17.12.3 because of stability.
