A few days ago, I passed DCUFD and earned my Cisco Certified Network Professional in Data Center! The test had some issues with it, but I think it was a fair certification to gauge if someone has been around Cisco’s Data Center product line. As with all tests, there are a few gotchas, but I

Fellow Cisco people, I am back! After a long hiatus, I have decided to stop paying my hosting provider tons of money to keep a blog with a few posts. I never stopped to think that SNMP was a topic people would have an issue with. SNMP versions 1 and 2c are easy to configure;

I am fortunate enough to be a part of a great group called NYC Networkers. I have been asked to come up with relevant topics in the networking area and teach them to members of the group who RSVP to the meetup. Last Sunday, I did a meetup on “Basic LoadBalancing Principals,” and a decent-sized

In my honest opinion, the tests were good. 640-911, I feel, was the tougher of the two, just because

I have been neglecting my fellow readers, but there is a good reason behind it. After my horrid experience in RTP in May, I took a long look at where I see my professional life going. After mulling it over for a long time, I have decided not to pursue my CCIE R&S. It was

First, let’s put a disclaimer on this post… I just got back from a HORRIBLE lab experience at RTP. This post may be extremely jaded, but I need to get this off my chest and pass or fail; I still feel the same way. I remember holding the CCIE on such a pedestal when I

So blogging world, it has been a while since my last post. Since my last post, I paid RTP another visit and did not leave with the prize; although my scores significantly increased, it still was not enough to get that coveted 5-digit number. Today, we will look at the lock and key access-lists and

During my lab time last night, I did a bunch of IPv6 transitional labs that I will be showcasing on my blog in the coming days. The first of these will be IPv6 NAT-PT. What NAT-PT accomplishes is it allows for bi-directional connectivity between IPv4 and IPv6 domains during an IPv4 to IPv6 transition. Our
