How Do I Upgrade a Stack?

How Do I Upgrade a Stack?

A stack can be upgraded using the traditional upgrade method (specify the next-startup files and restart the entire stack) or the fast upgrade function. The fast upgrade function applies to a stack with two member switches.

  • System restart

    1. Upload the new system software to the master switch and copy it to all the other member switches. If a member switch has multiple MPUs, copy the new system software to all MPUs.

    2. Run the startup system-software system-file all command to specify the name of the system software to use at the next startup.

    3. Run the reboot command to restart the stack.

  • Fast upgrade

    1. Upload the new system software to the master switch and copy it to all the other member switches. If a member switch has multiple MPUs, copy the new system software to all MPUs.

    2. Run the startup system-software system-file all command to specify the name of the system software to use at the next startup.

    3. Run the system-view command to enter the system view.

    4. Run the stack command to enter the stack management view.

    5. Run the stack upgrade fast command to start a fast upgrade.

      After performing a fast upgrade, you can run the display stack upgrade status command to check the upgrade status.
