RE: [WIRELESS-LAN] support of L2 peering devices?

2016-11-30 Thread Tim Tyler

Thanks!  I seem to have it working now, though I should probably test
another device.   I am not sure what I did.  I enabled the DNLA protocols
but I am not sure if that was necessary in AirGroup.  One of my problems
might have been related to not being logged into a gmail account when
testing.  It seems that the app won’t finish the connection though the
Chromecast device actually connects to the SSID and does allow apps to cast
to it.  So it does seem to work after all.  Thanks!

Policy based on AirGroup authorizations from ClearPass.



If I have a Chromecast/AppleTV/whatever on subnet A, when that device
authenticates to the network, the controller will send an AirGroup
Authorization Request to ClearPass. ClearPass will return sharing
properties of the device (personal vs shared and who it should be shared
with, ap group restrictions, time restrictions etc). At that point, the
device is placed into the AirGroup table on the controller.



When my client device in subnet B does a discover for services, any service
advertisements that I’m allowed to see (based on the policy from ClearPass)
will be send out onto subnet B by the controller.



Note that policy via ClearPass is not required, but recommended.

Tim,

  “subnet based on policy”?  I have a pool of 6 vlans of which devices get
randomly assigned to one of the 6 subnets.   How does Airgoup know which
subnets the two pairing devices are in?  I thought it required a broadcast
to find each other.  I would think that would require a broadcast going out
to all 6 vlans.I am not quite sure what you mean by “policy”.

  I should note that all Bonjour devices work fine.  I just can’t get
Chromecast and other peering devices to work.  And I have enabled just
about everything under AirGroup at one point or another.  If Chromecast
should peer across multiple vlan (subnets), then I may need to contact tech
support again.   I keep wondering what I am missing.

   We do have the AirGroup functionality enabled.  But I also have a pool
of 6 /23 vlans.  So my first question is did you set up an independent SSID
for L2 devices to register?   Did you use one vlan (subnet)?  What size?
I am curious about the details to allow broadcast, but I am guessing I can

It works on a request basis.   When "servers" advertise services, they get put 
in a central table.   When a client 
request the service the lookup is done on that table.   So airgroup does not 
cross subnets, it just needs to "see" each 
subnet so that is can respond to clients and add servers to the table.   The 
question is which part does not work?

for chromecast.

1. It does not work with 802.1x so can you properly configure it and get it on 
the network
2. Does the service get added to the table for the controller it is connected to
3. does the client properly request it and get a answer
4. Can the client actually route to and communicate with the server (this has 
nothing to do with airgroup)

I would start the test with everything on the same controller and same ssid.   
Then try moving the client to a different 
ssid.

We have successfully used airgroup for chromecast across subnets on the same 
controller.  I have had hit and miss luck 
with different controllers.

The AirGroup functionality in Aruba ClearPass is probably what you're looking 
for.  You can set it up so that when students register their devices, they can 
choose whether those devices are allowed to use broadcast/multicast to talk to 
their other devices, or even allow sharing to other users (potentially,

RE: [WIRELESS-LAN] support of L2 peering devices?

2016-11-30 Thread Chuck Enfield

We were told that for a 7240 controller AirGroup was limited to receiving 
(not necessarily responding to) 200 pps.  Given the typical amount of 
multicast traffic coming from client devices, I would expect 200pps to be 
reached at a tiny fraction of the 32K devices a 7240 claims to support.



Has anybody that uses Airgroup run into the limit of multicast packets per 
seconds that can be processed by their controller?  If yes, what has been 
the practical impact of hitting that limit?  If no, have you taken active 
steps to avoid it, or is my thinking incorrect and the multicast pps count 
is much lower than I expect?



Thanks,



Chuck

   We do have the AirGroup functionality enabled.  But I also have a pool of 
6 /23 vlans.  So my first question is did you set up an independent SSID for 
L2 devices to register?   Did you use one vlan (subnet)?  What size?   I am 
curious about the details to allow broadcast, but I am guessing I can ask 
that of an Aruba engineer if I need.  The ability to allow broadcast seems 
critical to getting Chromecast to work.

Tim,



The AirGroup functionality in Aruba ClearPass is probably what you're 
looking for.  You can set it up so that when students register their 
devices, they can choose whether those devices are allowed to use 
broadcast/multicast to talk to their other devices, or even allow sharing to 
other users (potentially, depending on your setup).



We've seen it work fairly well, although sometimes a chromecast or something 
will freak out and lose connectivity briefly with devices that it's supposed 
to be allowed to talk to.

find out the different methods that some of you might be using to support 
the most difficult L2 devices such as Chromecast, Sonos speakers, and other 
L2 devices that need to peer with another device in order to work.   These 
type of devices ultimately need to broadcast to see each other.  Chromecast 
generally needs to broadcast to the phone app so that the phone app can see 
it and establish a connection with one another.   If you create another SSID 
for it, what are the key factors in making it work?

Back in the earlier Fall, a number of you stated that you were using /16 
subnets or very large subnets so that you only needed one subnet for your 
residential wireless network.   So the question I have is did you do this to 
better support L2 devices?   If so, do you allow broadcasts on your large 
wireless subnet or did you simply do one /16 subnet to simplify the 
administration of your wireless network?

Bottom line, how are some of you supporting L2 devices that allow Chromecast 
and other peering L2 devices to work?

RE: [WIRELESS-LAN] support of L2 peering devices?

2016-11-30 Thread Cappalli, Tim (Aruba)

Tim,



Chromecast will work with the AirGroup service Googlecast enabled and with 
drop broadcast/multicast enabled on the VAP.



This can work in large subnets or multiple smaller subnets.
