I am attempting to join two identical Cisco 2960X switches into a stack at a remote branch office. I made sure both were running the same IOS version - 15.2(2)E5. However when the remote technician connected the switches, the logs showed a version mismatch.
After getting the switch back, I confirmed the IOS version was an exact match. However when I ran the command "show platform stack manager all", the Stack State Machine View is showing the version as 7.56. The other switch is showing 1.56.
This does not make sense to me as the Cisco documentation states that the stack firmware is set on the IOS image, so if the IOS image matches then the stack version should match as well. The minor version matches, but the major version is off.
To troubleshoot, I upgraded the switch showing version 7.56 to the latest recommended release, 15.2(2)E6. During the IOS install, the output showed clearly that the stack firmware was 1.56. However after the upgrade was complete, the show command still reports 7.56.
Does anyone have experience with this at all to explain what is going on and how I can get the firmware to match?
