The good news is that they appear to offer an "academic" license for
individual use (approval time ~1 week). The bad news is that when I
google "virtutech cisco switch," I come up with precious little. Here is
a link to a presentation where Cisco is mentioned in passing:
http://www.deserec.eu/files/first_workshop/pdf/DESEREC_IABG_Simics_Workshop_2006.pdf
It may indeed be possible to emulate a Cisco switch, but it appears as if
there exists no "Dynagen equivalent" for we mere mortals. And no real
history to indicate CPU/memory requirements (could you emulate one switch
with a given hardware configuration or could you emulate 12?). Certainly
there doesn't appear to be any "body of knowledge" out there. Also, not
sure how to take it, but that presentation makes mention of only being
able to bridge "TCP and UDP" from the simulated environment to a physical
NIC (so no control plane traffic directly over IP? etc?). Thus, I'll
keep my ear to the ground on this one, but I still plan to spend the next
several months tackling the CCIE R&S lab vs. being one of the first to
figure SIMICS and Cisco switches out...

Anyone who know mode about http://www.virtutech.com/products/ and how
to
simulate Cisco 3550/3560??

Objet : [Bulk] RE: Virtual CCIE's?
When teaching a class at Cisco recently one of the students said that
the
3550 or 3560 can be "virtualized" using software from this company:
http://www.virtutech.com/products/
https://www.simics.net/
Personally I never looked into it but someone here may be familiar
with
the software and it's capabilities.
