In this short but helpful post, I’ll go through the process of upgrading the ASA IOS via the ASDM. This is a pretty painless method if all goes well the only thing you have to do schedule downtime if this box is in production, and grab the ASA IOS image from Cisco. For this post all have been covered let’s get started! Continue reading

Basic Cisco ASA Overview
The Cisco 5500 Series Adaptive Security Appliances are of course an excellent firewall but the ASA also offers (depending on the model) other security services as well, like IPS systems, VPN, content security, unified communications and remote access. These ASA’s can be used as a standalone appliance’ that can handle the need for branch offices to enterprise data centers. Or they can be included in high-performance blades that work together with the Cisco Catalyst 6500 Series, and recently new they can also run in a virtual instance which provides tenant isolation for public and private clouds! For now let’s focus on the basics of the ASA like the ASDM. Continue reading
CCNA Security – 640-554
Out with the old and in with new Cisco is updating its well-known certification CCNA Security. Candidates that are studying for the older exam (640-553) are suggested to take it on or before September 30th 2012. What has changed in the exam? For the most part Cisco SDM is no longer covered, as it has reached its “End of Life” and in fact Cisco Engineering stopped covering the product from developing and testing on February 26th 2012. You can still renew the product for support (Cisco SmartNet) until March 24th of 2013 and the last date the product will get support will be February 28th of 2014 after that it will become an old friend

This was a long road to travel over a year ago I passed ICND1 which I recived the CCENT certification but with just general life getting in the way I also saw my chance of getting CCNA status stepping further in the distance. If you read how I passed ICND1 will find that the way I studied for this exam was totally different from studying for the ICND1.
What is the Nexus 1000v?
I have worked with the Nexus 1000v product and wanted to share my thoughts on it. I want to explain in this blog what this product is and what it does. The Nexus 1000v can be virtual or a hardware appliance and is considered to be a virtual switch that runs in VMware. The major benefit to this product is the visibly you get when running in a virtual environment. Remember in the virtual environment the network engineer has a cloudy vision of what’s going, because the built-in switch within VMware does not get that technical it just works. This is fine for most people but not all, especially the network technicians we want that visibly and the Nexus 1000v does that and more! Continue reading
