Cisco NX-OSv 9000 appliance

The NX-OSv 9000 is a virtual appliance designed to simulate the control plane of a Cisco Nexus 9000 switch. The NX-OSv 9000 shares the same software image running on Cisco Nexus 9000 hardware platform. Line card (LC) ASIC provisioning or any interaction from the control plane to rela switch ASICs are emulated by the NX-OSv 9000 software data plane.

Following the the Nexus 7000 Titanium emulator, the NX-OSv 9000 is a moder emulator for datacenter certifications training. It's also great plaform to test network automation prior to production deployment.

NX-OSv 9000 runs on GNS3, KVM, or VMware NSX. Current version of NXOSv is 10.4(1)F. This version adds or enhances VXLAN EVPN First Hop Security (IPv4), radius over DTLS, port-channel load-balance command for MPLS tagged traffic, support to redirect/deny all packets using ePBR policy, VXLAN QoS Outer Header Policy for Layer 2
