Thank you very much, now I'll try to perform some deployments over a C3600 w/NS module.

Unfortunately that is only a limited reproduction of what happens in a switch, making it a nice toy. Having an ability to simulate the execution of the IOS control software through CPU emulation is one thing; Real switches, including a real NM-16-ESW etherswitch module contain some proprietary hardware ASICs. RA guard, and similar functions are hardware features on switches that can sustain any sort of reasonable production load. GNS clearly tries to simulate the interface between a NM16ESW module and the host. But last I checked, no ASICs were being reverse-engineered for the benefit of GNS. Which would be one reason GNS cannot simulate Catalyst, and the reason NM16ESW is only simulated at a very high level. So, err, this is no replacement for testing RA guard on real hardware, sorry.
