• Issue gnoi.SwitchControlProcessor to the chassis with dual supervisor, specifying the path to choose the standby RE/SUP.
• Ensure the SwitchControlProcessorResponse has the new active supervisor as the one specified in the request.
• Validate the standby RE/SUP becomes the active after switchover
• Validate that all connected ports are re-enabled.
