Switches failing open - What about switches behind switches?

I was about to start testing the macof utility in the dsniff suite to try and get my switch to fail open and operate like a hub, but then realized at some hairy places on my network (some workbenches for example) there may be three switches in series. I may not care about any of the traffic until the last switch before the gateway to the outside world .. The choke point where all outbound traffic must pass. If I run something like macof against a switch with one or more switches behind it, what will the effect be? Will only the first switch fail open? Thanks!
