A factory IoT network will install a new system image on an MDS switch that has only one supervisor. The team wants forwarding to continue straight through the upgrade. What should they expect from this upgrade?
Select an answer to reveal the explanation.
Short Explanation
There is one driver in the truck, so the truck stops when that driver gets out to change seats. You should expect this MDS to stop forwarding while its only supervisor reloads onto the new system image. An EPLD update programs hardware logic, and it does not keep the data plane alive through that reload.
Full Explanation
A nondisruptive MDS system upgrade depends on a second supervisor that can take over while the other one loads the new image. This factory switch has only one supervisor, so installing the new system image reloads that supervisor and forwarding stops for the reboot. Expecting the upgrade to stay nondisruptive misunderstands the single-supervisor platform. The image is not swapped in place while the ports keep forwarding. An EPLD update programs programmable logic on modules and is a separate operation from the system image. It does not hold the data plane up while the only supervisor reboots into a new OS. NPV mode changes how an edge switch participates in the Fibre Channel fabric. It does not add a standby supervisor, and it does not let a system image load without a reload on a one-supervisor switch. Caveat: a dual-supervisor director can often move forwarding to the standby during an upgrade, but only when the images and the chassis actually support that hitless path. Operational check: confirm the switch shows a single supervisor, plan a maintenance window for the reload, and verify the new image and the VSAN logins only after the switch is back up.
