This week at Interop NYC, Cisco launched it’s ISR 4000 Series. This is a new approach for them focused on delivering services to your branch offices. Cisco has dubbed this new approach the Intelligent WAN (IWAN) — but before we talk about that, let’s talk about hardware. Those of us that have been paying attention […]
HP talks SDN at Interop NYC 2014
I generally try to avoid oversharing when it comes to my thoughts about presentations, but I have to mention that after sitting down with Glue Networks and their “SDN” presentation, it was truly a breath of fresh air to hear from HP. They went into some details on how they demonstrated the capabilities of their […]
Installing VMware tools on Cisco ACS
As of ACS v5.4 Cisco has finally included VMware tools for their ADE OS. Unfortunately, when you upgrade, they do not get installed automatically as the installation is triggered during the initial install. This post is for those of us that have upgraded to version 5.4 and didn’t choose to do a fresh install. First […]
Using Deny ACEs in your PBR ACL on your Nexus 7k
Quite a while ago I had a need for some network duct tape… Policy Based Routing while useful should only IMHO be used as a temporary fix. But as you know, temporary things soon become part of production and they end up staying around far too long. But I digress. I had a need for […]
Vendor PSA: Words and Phrases to Avoid in Presentations
Over the years IT professionals have sat through countless presentations, conference calls, and keynotes. We’ve been preached too, explained “the problem”, and forced to bear witness to the the future. During such events all of us have had to step up and explain that we already understand the problem, we know who your company is, […]
Cisco ASA Packet Captures for Fun and Profit

In order to succeed I’ve had to develop many new skills including learning Cisco Wireless, UCS, a little Fibre Channel, and of course Cisco ASA. While I have been using firewalls for many years, I’ve never […]
Fixing iMessage on Hackintosh
Mid December 2012 Apple shut down the Messages Beta for Lion, soon after many hackintosh users started noticing issues with signing into iMessage. At some point in time, people far smarter than me managed to patch a little used bootloader called Clover to allow us to log into iMessage, but Clover is young and still […]
Double NAT – Cisco ASA 8.4+
Recently I was faced with an issue outside my normal expertise… those of you that know me realize I am anything but a security engineer. But in reality, you must always expand your horizons. One of the projects I’m working on involves migrating between two edge networks. Obviously, for a time there has to be […]
Vim Primer for Network Engineers
Vi is arguably the best text editing software in the world. There, I said it… deal with it! It should be noted that while many people continue to refer to Vi simply as such, Vim (Vi improved) has been the standard since around 1998. Vi? Old and busted. Vim? New hotness. Vi isn’t an editor […]
Cisco Nexus 2000: A Love/Hate Relationship
My feelings towards the Nexus 2000 Fabric Extender (FEX) are hardly a secret. The myriad of design choices and platform limitations present engineers with some rather difficult decisions. Because of this, I’ve seen a handful of engineers reverse course on their current design due to limitations. It’s because of this that I have harsh feelings […]
