In our last test in the datacenter environment, we had deployed MSTP
according to Cisco recommended practices (pre-map all vLANs).  This wasn't a
large issue to us, as we really only have 2 paths through our datacenter
fabric.

However, on the Dell side, with the PowerConnect 5324s we tested, mapping a
vLAN to an MSTP instance attempted to create the vLAN on the Powerconnect.
This was a non-starter, and we stopped evaluating the platform.  The test we
did crashed the Powerconnect as it attempted to create 4000+ vLANs at once.
