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.
=46rom 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.
