Just reading around trying to find out what other schools are doing about these devices for the classrooms. We have some instructor interest in them, and all the posts about them I see are older, so I was hoping to see if anyone has gotten any of these devices working well.
We have Clearpass, Controller, Mobility Access Switches, and APs all from Aruba, so basically a full Aruba implementation.
If you have them working well, do you have any info on setting one up your could provide? (we seem to prefer chromecast as a company) I understand Airgroups are generally an expectation with these devices.
We block intra-subnet communication, and our thought is we would want to make sure that only our Employee and IT subnets could access these devices. I have zero experience with any of these devices, but we are mostly looking for the 'screencast' ability.

For screen mirroring, they both behave the same from a network standpoint.
The next Chromecast will be even better as it will be dual-band. The price point is expected to be the same ($35)

We have been wrestling with mirroring for a while and were very excited about the newest AppleTV with the latest software upgrade. Now I see Chromecast is worth a closer look.

We are experimenting with Chromecasts and like other consumer devices, wish they worked better in an educational environement.
Our controller is running 220.127.116.11. It is my understanding that 6.4 adds the architecture to make devices like Chromecasts work similarly to how AppleTVs work under 6.3, i.e., they are seen across VLANs and such things.
What we are currently trying is putting Chomecasts on an SSID with a PSK and assigning it to a VLAN based on its MAC address. This VLAN is the same one the client is on, which could be limiting for us if we want students to share their screen as students and teachers are on different VLANs. The clients are authenticated via 802.1x. While this works in general, we are having difficulty with the sceen casting option. Streaming from other apps works fine. When trying to cast the screen, it doesn't find the device, even though on the option to view devices they are listed. I've had a ticket open with TAC for a bit and they haven't been able to reproduce the issue. I talked with them yesterday and sent them backups, logs, etc.
An Aruba engineer was able to reproduce the issue in his lab. And a test I did with an IAP senario running 6.3.x, worked fine for screen casting. My gut feeling is a certain type of broadcast traffic is being dropped. Hopefully, TAC will figure out what the issue is soon as screen casting is a nice and wanted feature.

How to you ensure that students don't have access to the chromecast?
Another of our concerns is that we set up a chrome cast and a student would take over the screen and put something inappropriate on screen.
