The only disadvantage I can see for us is that licensing is not free. The network simulation platform by Cisco grew a lot and with its possible to simulate Nexus switches… and much more. The VM’s were very unstable, reloaded many times but it showed me it was possible and I confirmed communication between them. Some weeks ago I managed to run3 x NXOS inside a GNS3 VM with 100% of my available memory (a mere 8GB). With the image in hand, instead of configuring the VM by hand, its recommended you download and use the GNS3 appliance template for NXOSv here. While GNS3 is free, a legal NXOSv image requires you to pay for VIRL licenses. The tutorial shows how to do connect Titanium VMware image to GNS3 using Qemu emulator. A copy of Titanium 5.1.(2) installed on VMware image has recently leaked to the Internet and now we can use it for our studies. GNS3 easily allows you to simulate networks between VM’s, and now its even easier with the GNS3 VM. Titanium is Cisco Nexus Operating System NX-OS emulator made by Cisco. NXOSv its a virtual machine that simulates the Cisco NX-OS operating system. You can build topologies with one or more Nexus switches (and why not IOS XR in between?)įortunately, in this post I won’t go to much into the details on how to use DCloud. This demo gives you access to VIRL (Virtual Internet Routing Labs) and all its possibilities without having to buy licenses or having the minimum prerequisites to run it in your own PC. This lab is prepared to show Python programming features in NXOS (similar to TCL in IOS).

Charming the Python on Nexus 7000 Switch v1 Since these are minimum release recommendations, more recent software releases can be used to take advantage of newer hardware and software capabilities. The objective of this demo is to know the NXOS interface with a Nexus 7000. This document lists the minimum recommended Cisco NX-OS software release for use with Cisco Nexus 5500 Series switches for both new deployments and existing deployments.

Cisco Nexus 7000: Introduction to Cisco NX-OS v1 The links below are for the demos I found and allow you to login to a virtual Nexus switch. Most of the demos also have a script to follow but nothing prevents the user from diverting from this script and doing whatever they want. The portal is completely self-service with well written guides on how to use it and every specific demo. Cisco DCloud (Demo Cloud)ĭCloud its a free portal for demoing of Cisco products.

None of them gives you access to an actual, physical switch. My suggestions for the good of knowledge and our pockets:īefore going further, lets make it clear that all these are virtual and based on the NXOS “Titanium” project. But how do I get some hands-on experience without having to spend thousands of dollars? Of course, I decided to start looking at the Cisco Nexus and the NX-OS operating system. Lately I have been focusing my studies in Data Center technologies.
