As an aside, PVST can become an issue when you're scaling up into

The 3560/3750 series supports only 128 PVST instances. I discovered this
the hard way.
I just went searching for this to find the limit for 3550s, and couldn't find
it. Anyone have a pointer to where in the docs cisco says how many
rapid-pvst instances can be done on the 3550 and 6509?
For the 3550:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/12.2_25_see/configuration/guide/swvlan.html#wp1353846
It is hidden in the Supported VLAN configuration secion
