One of the cool new features added to the reporting engine in the latest release of our NetFlow and sFlow Analysis tool is the Advanced Filter option. This filter lets you filter the data in any report on any field that is present in the exported template. So filtering reports on things like MAC addresses and Vlan ID’s are all possible.
Let’s take a look at a cool use of the MAC address filter.
We have our Cisco wireless access point plugged into our Enterasys N series NetFlow capable switch (PLXRSW1). This allows us to look at the volume of traffic coming from the wireless devices.
The above is useful, but I wanted to narrow in on the hand held devices. Specifically, I wanted to find out how much traffic is placed on the network when a person streams a NetFlix movie to their hand held.
