Last school year we ended up rolling back AP firmware because Apple TVs on our student wifi began having connection issues immediately after updating our MRs. This summer we went ahead and updated all APs to 30.6. We are again having connection issues. All of the ATVs are visible to devices (MacBooks and ipads on the same wifi), but when trying to connect it either takes forever, never asks for the passcode (enforced by MDM) or does nothing. And of course it's random among versions (some tvos 17.5.1 work great, some don't for example). If I remove the wifi settings from an ATV (forcing the device and ATV to use a direct wifi connection) everything works great. The wifi is pretty straight forward, bridged, WPA2 password, no layer 7 firewall rules and the usual allows for bonjour, dns, etc. I don't believe it is a firewall issue as some connections work just fine. Thanks for listening

Yes, trunks allow all So I have another stack of 8 Alcatel switches in the MDF that is connected to the fiber stack. It is the root, not the fiber switch stack Alcatel are RSTP Ciscos are pvst+

Hi everyone. Last summer we deployed 10 MS125s, one to each IDF in the building. Each MS125 has two fiber connections back to a stack of two Alcatel fiber switches, one fiber to each side of the stack for redundancy. Both the Meraki and Alcatel side of these aggregate links are configured LACP. Our network also has a number of older Cisco switches with separate single fiber connections back to the Alcatel fiber stack (although this is probably not relevant, just fyi) While traffic seems to be flowing just fine, each one of the MS125s has been reporting "high rate of stp topology changes" since the very first day of deployment. Our Alcatel service provider confirms that the link aggs are all configured correctly. The Alcatel fiber stack log does not indicate a high number of stp topology changes. I've noticed that each aggr link (51,52) on each Meraki reports different LDP/CCP info. 51 shows just just the link back to the Alcatel fiber stack (which is what I would expect): Port 52 shows a list of every switch on the entire network (which seems odd): As I mentioned, traffic seems to be flowing just fine, but I'd thought there might be a solution to the reported stp topology changes (are they even really happening? Also, I believe this is why the Meraki topology map is different and incorrect every time I check it. It shows switches connected to other switches that are not connected that way. Indeed, we have a fairly straight forward star shaped network Any thoughts?

I think I may have found the problem. Student SSID is NAT, teacher SSID is bridged. Evidently clients connected to the same AP in this scenario will not see one another - even if L3 rules are configured. Wondering if around 1100 ipads is too many to switch my Student SSID to bridged

Yep, that's what I meant by bridged ssid in the subject. 3285 is no longer necessary, although I did give that a shot but no joy. If I try another bridged SSID with no firewall rules at all, things work as expected. So, I'm trying to figure out what specifically is being blocked by the default deny so that I can allow it

Yep, I understand that. What I'm trying to figure out is when I change that to Allow, Apple classroom works. So what exactly is it allowing so I can make an explicit rule and change the catch-all back to deny.

Hi folks - i Allow 3284 (tcp) and 3283 (tcp/udp) in my layer 3 firewall rules. Layer 2 Isolation is disabled. Student and Teacher iPads are on the same SSID. Student iPad reports as Disconnected in System Preferences. Teacher Classroom app shows all students "Offline" Connect both iPads to my phone hotspot, Classroom works Remove "Deny - Any - Local Lan - Any" from my layer 3 firewall, Classroom works Cannot tell what that last rule is denying - any thoughts?
