As you probably know one have to take in account the max available numbers of virtual ports and logical interfaces for Spanning Tree when designing a switched network based on catalyst 6500's. Does somebody know if you also have these parameters if you're designing a network based on 4500's or 3750 stacks? And where to find it on the Cisco site

Number of VLANs and SVI supported per catalyst family is not always the same. For example a switch may support 256 VLAN , but only 64 SVIs.
cisco cat switches support up to 4096 VLANs depending on the platform and software version.
Cat 6500 -- max No -4094.
Cat 4500 -- max No - 4094.
Cat 3750 -- max No -1005.

My issue deals with Spanning Tree Protocol or better the scalability of STP. see the following document:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/122sx/ol_4164.htm#wp26366
For choosing the right spanning tree protocol (RPVST+ or MST) you have to take logical interfaces and virtual ports into account on the 6500 platform. But what if you decide to use a different platform, for instance a 3750 stack.
