Apple TV

We were running into issues with getting Apple TV to work on our wireless system.  We are running a Cisco wireless infrastructure.  The Apple TV would work as far as getting internet access and was able to stream video and sound to the TV, however when you used Airplay on an apple phone to stream its contents to the TV nothing would happen.  The confusing part was we have Apple TV’s working on campus in other areas of the campus.  After working with one of our network gurus we discovered the issue was actually a security setting that did not allow node to node discovery and communication.
