Enterasys and apple tv mirroring

[Laura4]

We have Enterasys APs in our school. We also have apple tvs and ipads and mac books. We are having issues mirroring to the apple tv. The list of apple TVs to mirror to does not always populate with all the tvs in the school. Does the apple tv and ippad/macbooks have to be attached to the same Enterasys AP to mirror successfully?

Are the "missing" Apple TVs in the same VLAN as the ones that you do see?
One of the requirements of Apple's Bonjour service is that devices are in the same broadcast domain so that they can be discovered. They can be on different APs (and even different SSIDs) as long as the network behind them is the same.
