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.
