Disabling or re-enabling the auto image copy process for a Campus Fabric (SPX) configuration

The auto image copy process is enabled by default but may be disabled.
You can use the image-auto-copy disable command to disable automatic image updates if you want to run different software versions on different units of a stack. This can be useful, for example, if you want to try out a Ruckus patch image on just one unit.
  1. Check whether the auto image copy process is enabled by using the show stack detail command at the Privileged EXEC level on the stack active controller.
    The auto image copy process is disabled in the following show stack detail command output for an ICX 7750 traditional stack. 
    ICX7750-48C Router(config)# show stack detail

  2. To re-enable auto image copy, enter the no image-auto-copy disable command in global configuration mode on the active controller as shown in the following example. 
    ICX7750-48C Router(config)# no image-auto-copy disable
