Changes in the Cisco CCNP Certification Track…
How long ago was it that Cisco changed the CCNP test track? How long have I had my professional cert? Am I getting old? Anyway… Times are a changing! Cisco has once again changed the CCNP track! They are dropping all of the tests and introducing three new tests: 642-902 ROUTE 642-813 SWITCH 642-832 TSHOOT Too easy right? And if you have already started the old track, do not worry! The old tests are still available until July 10,...

Many of you are going to read this short article from Computer World and say, “Dan, I do not give a damn how the onlines work as long as I can reach my Facebooks!” Well, I just want you to think about the staggering amount of data this piece of equipment can process.

I spent a large part of today working with an engineer on the IOS Zone-Based Firewalls concept.

The bug was long thought to be fixed, but I found it again a few days ago in 12.4(24)T2 running on a Cisco 2801 at a customer site. Said customer had a security camera system installed that had a centralized DVR. They wanted to be able to view the DVR output both internally and externally. The camera integrator requested a 1-to-1 NAT relationship which I provided. We were able to...
