Tips from the Field

Aruba Networks Scottsdale Airheads

I hope that you were able to attend the Scottsdale Airheads conference this week, it was a good time and I actually learned a few things.  All of the attendees received an Aruba RAP-3, which is the latest generation of Aruba's smallest remote access point.  I got my RAP-3 home, unpacked, configured and running in about 10 minutes...piece of cake.  The RAP-3 can be used a a traditional remote access point that tunnels back to an Aruba controller, or it can be used as an "instant" AP.  If you don't know about

Palo Alto Firewall Schedules

Recently we had a request from a client to create a schedule for their Palo Alto Firewall that would restrict access to social media and streaming media. The client wanted to restrict access between the hours of 8:30 PM and 6:00 AM. The client is running the 4.1.7 operating system on their PA-5020. Initially the client tried to setup the schedule as recurring weekly schedule Monday-Thursday from 20:30 - 06:00. The policy was not being hit when we looked at the traffic logs.

Data Center Bridging

The last bastion of proprietary networking is continuing to thrive within data centers. SANs based upon good old fashioned fibre channel still support 99% of the world’s storage resources. To their credit, fibre channel networks are extremely reliable, provide high performance, and are simple to administer. On the other hand, they are quite expensive (especially when compared to Ethernet), and they are truly isolated from the rest of the network.

Watching the Olympics at 30,000 feet

I just love technology, on my flight home from Cincinnati last night I connected to the Delta GoGo Internet service and was able to watch the Olympics being streamed from my Monsoon Vulkano at my house on my Asus Infinity tablet.  On commercial breaks I changed channels and watched the Dbacks baseball game.  There were a few times when it go a little pixelated, but the sound never cut out.  Quite amazing...on my next trip I am going to try a Microsoft Lync call and see how that goes.  I've tried this little experiment in the

Dell/Compellent SC8000 Controller


Finally got to do our first Dell Compellent SC8000 SAN installation today.  The new SC8000 controllers are based on the Dell r710 servers, no more SuperMicro components.  The one thing that really stood out for me, even though it has nothing to do with technology, was the way the controllers were shipped.  The packing is much more efficient and probably more environmentally friendly due to the smaller/compact boxes.

Palo Alto Firewall Update 4.1.7

PAN-OS Version 4.1.7 has been released. You can read about the new features and bug fixes here.

Note: In order to upgrade to PAN-OS 4.1, the device must be running PAN-OS 4.0.0 or later. Attempts to upgrade to PAN-OS 4.1 from earlier releases will be blocked.

Mobile Enterprise Security

We have all spent a lot of time talking about the perils of open-door BYOB policies.  The attached white paper by the Enterprise Strategy Group (ESG) takes a quantitative look at the impact of BYOB on typical enterprises.  This paper discusses the challenges (especially security) created by all of the new mobile devices and the “de-perimeterization” of organizations.  And finally it recommends some architectural solutions for these security issues.  In particular, the paper addresses – at a high level – mobile device management solutions.

How to rename an Aruba AP Group

Recently I ran into a situation where I needed to change the name of the AP Group on the Aruba controller. The only way I have been able to find to do that is via the CLI.

IPv4 Address Depletion

I wanted to pass this along from a friend of mine at Juniper Networks - Bill Kine.  As you probably know, the Internet registry is completely out of IPv4 addresses. The regional registries are also running out of their meager supplies of addresses. So, why hasn’t the Internet World ended? 

Windows 8 Task Manager


I've been playing with Windows 8 for a little over 24 hours and so far so good, I'm still getting used to the Metro UI.  One thing I do like is the new task manager in Windows 8.  You can now see the current state of the processor as it changes speed, if you have your computer configured to use the balanced power options.  I also like the new layout and performance graphs.  I think I'll give Windows 8 a full month before I decide whether or not to stick with it.  I do miss the start button and seriously hope the final version of Windows 8 has the ability to turn off the Metro UI.
