According to the documentation on the Cisco site:

http://www.cisco.com/warp/public/473/145.html

The 3550-12 is only capable of handling 16 SVIs in hardware (regardless of 
SDM template), after that you get into "resource exhaustion" which means 
it add the SVIs, but will go back to software/CPU-based routing.  Does the 
3550/3750 give any indication that it's in this state (software routing) 
other than melting under high traffic volumes?

We're currently waiting on Cisco getting back to us on figures for the 
3750, but given that it has a similar TCAM setup to the 3550-12, I'd doubt 
it would be different.
