How to upgrade Nexus 7K NX-OS Emulator Titanium VMware image to 6.1.1. Published March 15, 2013 by john. Setup Network Environment for Upgrade.

Lately I have been focusing my studies in Data Center technologies. Of course, I decided to start looking at the and the operating system.

So far, so good. But how do I get some hands-on experience without having to spend thousands of dollars? My suggestions for the good of knowledge and our pockets: • Cisco DCloud (D=Demo) • NX-OSv Titanium in GNS3 • VIRL (Virtual Internet Routing Labs) Before going further, lets make it clear that all these are virtual and based on the project. None of them gives you access to an actual, physical switch. Cisco DCloud (Demo Cloud) its a free portal for demoing of Cisco products. The portal is completely self-service with well written guides on how to use it and every specific demo. 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.

To access the portal you need: • Internet • cisco.com account • Understand english • Time Simple! The links below are for the demos I found and allow you to login to a virtual Nexus switch. Cisco Nexus 7000: Introduction to Cisco NX-OS v1 The best option to start. The objective of this demo is to know the NXOS interface with a Nexus 7000.

Charming the Python on Nexus 7000 Switch v1 This lab is prepared to show Python programming features in NXOS (similar to TCL in IOS). VIRL Sandbox The most complete option. This demo gives you access to and all its possibilities without having to buy licenses or having the minimum prerequisites to run it in your own PC. You can build topologies with one or more Nexus switches (and why not IOS XR in between?) Fortunately, in this post I won’t go to much into the details on how to use DCloud.

All demos have detailed documentation. But if it interests you. GNS3 com NXOSv Titanium NXOSv its a virtual machine that simulates the Cisco NX-OS operating system.

Easily allows you to simulate networks between VM’s, and now its even easier with the GNS3 VM. While GNS3 is free, a legal NXOSv image requires you to pay for VIRL licenses.

With the image in hand, instead of configuring the VM by hand, its recommended you download and use the GNS3 for NXOSv. Some weeks ago I managed to run3 x NXOS inside a GNS3 VM with 100% of my available memory (a mere 8GB).

The VM’s were very unstable, reloaded many times but it showed me it was possible and I confirmed communication between them. VIRL (Virtual Internet Routing Labs) The network simulation platform by Cisco grew a lot and with its possible to simulate Nexus switches and much more. The only disadvantage I can see for us is that licensing is. But if you can go ahead please.

B-Prepare your Environment. After you finished the step A now you are ready to build the lab as below. -Adjust GNS 3 configuratio n for instance Project directory, IOS i mage path, Dynamips ports and GEMU g uest. - Clone the Titanium NX VM from the VMware work station.

- Add IOS image for Cisco 3725 router. C-Configure Titanium VM version 5.1-cl1 and GNS3.

The configuration of the QEMU host is very sensitive if you make it not like this it will give you error. QemuImage path to the VMware flate disk ( vmdk-flate) file each nexus connect to i ts own VM I said before we will use 2 VMS for each Nexus 7K, RAM: 1024 MB, N umber of NICs 6, NIC Model e 1000, QEMU options lea ve it empty and last unchecked use KVM (Linux Host Onl y) as in the bel ow image.
