Upgrading MLAG-STP Setup

To upgrade NVIDIA Onyx on an MLAG-STP setup from 3.6.610x to this version, there are two possible procedures:

Procedure 1

  1. Make sure there are no loops in the fabric.

  2. Disable STP. Run:

    switch (config) # no spanning-tree

  3. Perform the upgrade according to steps 1-10 in "Upgrading Operating System Software".

    switch (config) # spanning-tree

  4. Once the MLAG stanby switch is back online with the new version, use "show mlag" and "show mlag-vip" commands and verify both processes are up. Next enable all ports on the MLAG stanby switch, and verify all ports are back online.

  5. Upgrade MLAG master according to steps 1–3 above, and use the below command to reboot the master:
