For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the battle was lost.
For want of a battle the kingdom was lost.
And all for the want of a horseshoe nail.
At WiFi Trek2016 the discussion of Wireless Packet Captures with 4 or more spacial stream AP(s) was discussed. Currently, I use a Mac Book Air and the program Airtool to take a packet capture and then analyze it in Savvius OmniPeek. The Mac Book Air has the capability to see up to three spacial streams. What happens when a new site is deployed with Cisco 3800 series AP(s) with four spacial streams? How do you capture those packets?
Certainly one way is to use a Cisco 3800 series AP as a sniffer tool. But another way is to disable the spacial streams of the radios down to three or two. This is a disruptive change, but it can be a work around if you need to see the traffic.
What are your thoughts on the topic? Do you have another plan or idea? Let me know!
