Confirming traditional stack software versions

All units in a traditional stack must be running the same software image. To confirm this, check the software version on all devices that you want to add to a traditional stack. Upgrade any units that are running older versions of the software before you build the stack.

To check the software version for each stack member, perform the following steps.

  1. Use Telnet or SSH or connect to any of the console ports in the stack.
  2. Enter the show version command. Output similar to the following is displayed.

    NOTE
    If any unit in the traditional stack is running an incorrect version of the software, it will appear as non-operational. You must install the correct software version on that unit for it to operate properly in the stack.
