It’s no secret the BYOD (Bring Your Own Device) revolution is in full swing, and you need to know how to monitor iPAD HD traffic on your corporate network. Long gone are the days where network administrators can police employees based solely on their desktop computer traffic. Cubicles are filled with 4 generations of iPhones, a variety of new e-readers, and now the new iPad HD / iPad 3.  BYOD network traffic analysis is of paramount importance.

If you read my previous blog on “NetFlow For Dummies” then you are already exporting NetFlow on your network. If not, what are you waiting for? It only takes a few minutes and  even comes with a free gift! Well, the gift is the never before seen insight available into your network infrastructure. In my IT administration world, bandwith traffic insight is priceless.

“Why should I be worried?” you ask? The answer is simple, these devices are using corporate bandwidth more than you are aware. Plixer’s own Scrutinizer Product Manager, Michael Patterson, had this to say on the subject:

“Despite the increase in productivity, some employees like to respond to their turn at Scrabble or to respond to personal Skype messages and the like.  In the old days, companies could check the phone bill to see if an employee was making or receiving excessive personal phone calls during the day.  The employee was then either given a warning or had to pay for the extra cost. Most often other employees took notice and did not repeat the offense.”

If you are not using a netflow analyzer, you may as well be monitoring your network wearing a blindfold. Need a suggestion? There is a free netflow tool on our website. Using the new Advanced filter option in your NetFlow reporting tool, I filtered for the first 3 octets of the MAC address of apple devices (60:33:4b & 64:b9:e8). Immediately after adding the filters, I saw the traffic I wanted to narrow in on.

 I’ve provided a screenshot as an example. This device was sitting “idle” on a network for 1 minute and 10 seconds and look at the flow volume it has produced. Whether it’s games, email, youtube, facebook or text messaging (iOS5 started using your network for that too), your networking is constantly being hammered. Multiply this by the amount of employees who come to work with these devices and now you are starting to uncover the scope of this problem that you may not have even known existed.
