CCNP Preparation : VIRL simulator
A virtual version of the Cisco Nexus 9000 datacenter switch is now available for CCNP Datacenter training : Nexus 9000v (or NX-OSv 9000) switch. Nexus 9000v is a virtual machine running the Cisco Nexus 9000 Series software image. It requires the following resources to run :
- CPU : 1-4 vCPUs (not oversubscribed)
- RAM : 8G memory for complex topologies and enabling features
- Storage : 4G hard disk
- Connectivity :
- 1 serial port
- 1 network interface card
All the Nexus 9000 features are supported except the following table :
NX-OS Features | Limitations |
|---|---|
QoS | Not supported on NX-OSv 9000. |
BFD | Not supported on NX-OSv 9000. |
ACL | Not supported on NX-OSv 9000. |
Policy maps | Not supported on NX-OSv 9000. |
ARP Suppression | Not supported on NX-OSv 9000. |
SPAN | Not supported on NX-OSv 9000. |
IGMP Snooping | Not supported on NX-OSv 9000. |
AMT | Not supported on NX-OSv 9000. |
LISP | Not supported on NX-OSv 9000. |
OTV | Not supported on NX-OSv 9000. |
Nexus 7000 Titanium NX-OS simulator has been included by Cisco in their new VIRL (Virtual Internet Routing Lab) simulation platform. Compared to Packet Tracer 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.
