If I were to enable spanning tree globally on an S4, would this cause an outage as the topology was established? Should I expect a blip, a few seconds, a few minutes, anything at all? Would it matter if all of the ports were set to disabled prior to doing this (to minimize any service interruption)?
I've read the relevant documentation on the S-series and spanning tree, but it doesn't say anything about the immediate effects of enabling on a production system.
