IOS/ Android Airgroup issues

 

Hi,

I'm in the process of configuring some simple Airgroup access on our dev mobility controller ( 6.5.2.0)

 

Server devices - Apple TV3, Chromecast2 audio , Chromecast2 UD

Clients - Android 7 tablet, IOS 10 iPhone

Primary app Plex - audio and video streaming but also use BBC iPlayer and  Spotify

 

2 SSIDs , airgroups-ipv6 and  airgroups-ipv6-psk performing WPA2-Enterprise and WPA2-PSK authentation. For -psk you also have to have client adress in a static ost list in clearpass and only devcs with specific DHCP signature are allowed on, else you get an access-reject sent.

Both SSIDs place a device on  the same VLAN and IP address assignment via DHCP IP Pooling.

On the mobility controller .....

 

Authentication assigns a speific Airgroup Role with a policy of "allowall"

 

Controller AirGroup services selected ... everything except remotemgmt and allowall

 

Airgroup Global settings 

All enabled except AirGroup Active Wireless discovery

 

Clarpass cluster set up as AirGroup CPPMserver

 

Airgroup Domain defined a UoY

Vlan table 

multiple  vlans defined but only two used for airgroups

 

237 for wired devices with both ipv4 and an ipv6 IP address

496 for wifi devices no ipv6 ip address assigned to controller 

 

All other vlans  disabled 

 

Controller Airgroup policy. 

For apple TV have user group defined as its a wired device doing dot1x 

 

An android device can see and 'cast to the Apple TV, and both audio and video chromecast devices

 

An iOS device can only see and stream to the Apple TV

iOS Google home app can see the Chromecast devics, no other app on the iOS device can even see the devices

 

On a normal home network ... iOS can see and cast to ChromeCast devices

 

Wired devics on 144.32.230

Wwifi devices on 10.241.252.x 

show airgroup blocked-service-id  gives

fe80::a6e4:b8ff:fe87:89a _invoke._sub._bp2p._tcp 36

 

and more ......

 

enabling "allowall" airgroup service makes no difference

 

SSIDS have 

Broadcast/Multicast  DMO enabled

Dro Broacast and unknown multicast  enabled

Convert Broadcast ARP reqiests to unicast enabled

...o.k. getting better .... the You tube app works on ChromeCast Video from iOS .... but bbc iplayer doesn't

 

Looks like its more down to the apps on the iphone

Re: IOS/ Android Airgroup issues

Does beg the question though why iOS at home sees everything and it "just works"

You should turn off Airgroup and turn off broadcast filtering to emulate your home network.

Re: IOS/ Android Airgroup issues

But we can't do that in our production environmnt. Are their any details anywhere of what the diffeences are between "home" and "enterprise" Airgroup functionality?

That is for testing to see if the problem is the infrastructure or the IOS device.

Re: IOS/ Android Airgroup issues

Hi,

did you solve this Alex? We are seeing the same behaviour, we are on 6.5.3.1, the iphone can see the chromecast via the google Home app. But not able to cast to it via Apps. 

 

Android and Windows work perfect.
