Just wanted to put this up has Cisco has recently released VIRL. This is a network simulation platform that you can run Cisco operating systems on which are the same operating systems that run on Cisco hardware so anything you do in this simulation environment would be realistic if it was running on dedicated hardware. You would be able to test your changes before throwing them in production.
Some things that are different between VIRL and CML (Cisco Modeling Labs)
- CML is Cisco TAC supported so you can call Cisco. With VIRL you have community to help you out.
- You have cap of 15 devices with VIRL. The CML version capacity is dependent on the hardware its running on.
- CML is for the “Big Guys”, and way more expensive. VIRL is just for personal/training use. (i.e CCNA, CCNP, CCIE)
To be upfront I have not purchased VIRL so I can’t tell you my thoughts on the product itself but personally I think this is great way to learn and study Cisco certifications when looking at CCNP and even CCIE. This is way cheaper than buying hardware or renting rack space. The price is $199.99 a year and I would assume this would cover any updates the product has. Cisco is also selling an Academic Version for $79.99 a year with some extra terms attached to it.
I’m curious if anybody has any thoughts on VIRL, what advantages do you think this network simulation program (VIRL) has compared to GNS3? What do you think VIRL’s target audience is? Is this price too high? Finally do you think the product is too green? Are you going to buy it or wait and see?
Just like before if you have followed, I have gone over the CCNA Data Center Study Guide from Todd Lammle and in this post we cover two chapters. Feel free to comment below if you have any questions on either of these two chapters. Continue reading “640-911 (Chapter 10 & 11)”
If you made it past the earlier chapters this one should be interesting, like before I am going through each chapter of the CCNA Data Center Study Guide from Todd Lammle. Comment below if you have questions in this chapter, last week we learned about subnetting and in this chapter we will learn about the NX-OS which is Cisco’s Data Center switches. Let’s begin! Continue reading “640-911 (Chapter 7)”
Continuing where we left off on Chapter 3 on CCNA Data Center Study Guide from Todd Lammle. Like before feel free to post questions below. In these post I am only going over the topics of each chapter of the book, plus any examples the book offers and to get an idea of what the Cisco exam would cover. In chapter three we discussed about Ethernet Technologies and in chapter four we will learn about the TCP/IP protocol which is fundamentally the protocol that makes the Internet work.

Cisco recently published its 2014 Annual Security Report, and some interesting data was captured in 2013. One of the details was a talent gap in network security and because of this gap Cisco has a major revision in the CCNP Security certification starting in April. Its estimated that in short term or already present is shortage of more than a million security professionals worldwide! Continue reading “CCNP Security Refresh”
