When completed, the supervisor kickstart image, supervisor system image, the linecard image and the
system BIOS are all updated.
Nondisruptive 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
unable to log in to the fabric via the control plane, but existing devices will not experience any disruption
of traffic via the data plane.
Before attempting to upgrade any software images on these fabric switches, follow these guidelines:
