Need some clarification. Is spanning-tree uplinkfast needed only when running PVST?

    You don't have to use it unless you need less than 30 seconds of convergence time. RSTP would be preferred if it is supported by the hardware.

    Sorry I should've been more specific with my question. I was referring to PVST with UplinkFast compared to Rapid PVST or say MST with enabling UplinkFast. If I'm running Rapid PVST or MST, would enabling UplinkFast be redundant? I hope my question is making sense.

    I can't remember the specifics for MSTs ports, its been a while since I learnt anything for it and used it. However for RSTP, Uplinkfast is a bit redundant as there is already the Alternate port role, which does pretty much the same job.

    Enabling uplinkfast won't do anything if you are running RSTP. I guess you could say it would be redundant.
