I've not had the pleasure of setting up air group etc, but found myself having to that a few times recently. I understand Airgroup is used to discover devices across different vlans.
After discovering, if you wanted to connect and do a mirroring, then that traffic would be unicast, correct?
So, any firewall between the two vlans would need to permit that traffic....and obviously needs to be routeable?
Thanks Tim....I thought as much. So in terms of the firewall on the Aruba, that would just need to allow 'apple-airplay', or is there any other I should let through as well?
UPDATE. I'm going a bit round the twist with this now, and the mirroring is not quite working for some strange reason.
What we are seeing is the following.
Doing a packet analysis, we found the following.
Given we can stream a Youtube video easily, it is rather frustrating.
Any suggestion greatly appreciated.
ok, so after reading some other threads and observations today, it turns out ipv6 is necessary for the mirroring to work.
Here's another thing we found though. When connected to the same AP as the TV, it works across vlans. When connected to a different AP than the TV, it doesn't work.
ok, so turns out there were some additional UDP ports that needed to be allowed through the firewall. It is all working fine now.
Interestingly, when on the same vlan, the communication between the device and the AppleTV is ipv6.
"ok, so turns out there were some additional UDP ports that needed to be allowed through the firewall. It is all working fine now.""If my post is helpful please give kudos, or mark as solved if it answers your post."
A list of ports could have been usefull...
