Re: Nexus emulation? Anyone?

I don't think anyone is asking for a full simulation of the platform in software, that is how the actual ASIC's
operate. That is probably best for an entirely different conversation.
But there is huge need to simulate the control-plane functionally with a basic forwarding ability (not performant, but
pass packets correctly such that you can verify the topology). This is something Dyanmips does great in emulating a
cluster of 7200's and allows operators to validate topologies and planned changes in mainstream IOS platforms. Having
that for NX-OS would increase the adoption and confidence in the platform. VM's on multiple boxes make simulating a
whole network of a given platform simple and easy.
From the outside Cisco continues to miss the need for this. At least some of the other vendors are picking up how
helpful this and are reacting positively to it.

You couldn't use Titanium to judge/discuss the nexus family as a whole either. Aside from 1KV, all the nexus products
use ASIC hardware specific to that platform/linecard and no NXOS software emulator exists that mimics those behaviors.

Check out this discussion
Titanium as they call the NX-OS simulator is not available to the public

Bah. Look like I need more of an education on Nexus in general. Thanks for
the easy pointer.

I know we can't throw NX code on Dynamips but I figured I would ask the
group anyway. We are starting to discuss Nexus platform options and I can
only get so much from demo depot before our AM gets whiny. Is anyone
currently emulating Nexus on anything that is open to the public?
