Non-disruptive upgrades on these fabric switches take down the control plane for not more than 80
seconds. In some cases, when the upgrade has progressed past the point at which it cannot be stopped
gracefully, or if a failure occurs, the software upgrade may be disruptive.
During the upgrade the control plane is down, but the data plane remains up. So new devices will be
Note
