A new version of the Titanium NX-OS simulator has been released and included by Cisco in their new VIRL (Virtual Internet Routing Lab) simulation platform. Compared to Packet Tracer 6.2, VIRL uses real cisco IOS, IOS-XR, NX-OS images running in virtual environments. The NX-OS simulation platform is now named NX-OSv and features a Nexus 7000 switch running NX-OX v7.2 . NX-OSv can be used in GNS3 labs and linked to other Cisco devices like CSR1000V or other vendors simulated devices. This new simulation environment will help students preparing CCNA datacenter or CCNP by overcoming Packet Tracer limitations.
