Re: Aruba OS 6.4 and Google Chromecast

cjoseph, I agree. And we all understand that these are consumer products and are willing to be patient while the bugs are found and addressed. On the other hand, these are extremely powerful tools that can't seem to be matched in the enterprise. We have an Apple TV in each classroom. What tool made for the enterprise can do what an Apple TV can do, in regards to full screen mirroring, as well as applications? I can't think of any.

 

We're on Spring break right now and it's a perfect time to dive into this. Apple TV use through Airgroup has been getting more reliable with each release. We're not even looking into implementing Chromecast devices in the classroom but we do have Faculty and Students living on campus. And for them, these things need to work.

Re: Aruba OS 6.4 and Google Chromecast

Any updates on this?

 

I have 3 IAP-103's with Virtual Controller setup. 2 of the chromcast are less than 5 feet from the AP. and roughly 30-60' from the other 2 AP's. But they keep randomly switching to further AP's at which time the dissapper. Plus the Role randomly switches from the SSID name to Unknown 105. 

 

We've tried both iphones, android phones, tablets and a mac laptop and still have inconsistent results. With a system reboot, all the chromecast show up great for a few hours, then they start not showing up as options anymore. They do however always show connected to an AP, just don't show up as a stream to option.

Cory,

 

 

If you have a Chromecast that keep switching from access point to access point you should:

 

1 - Make sure that the MAX TX power in the ARM profile on the IAP VC is no more than 18.  While you are at it, change the Min TX power to 12 or below.  Clients will bounce from access point to access point if the access point power is more than the client's output power.

2 - Turn off ClientMatch on the IAP, because that could exacerbate things if issue #1 exists

3 - Test to see if things improve

Re: Aruba OS 6.4 and Google Chromecast

Like Cory, I am having an issue where my Chromecast(s) disappear from being an AirGroup server, I don't have any wireless connectivity issues with my Chromecast(s). I am running 6.4.2.6-4.1.1.8_50989 on an IAP-205.

 

I have "Enable Bonjour" checked and the following Airgroup Services checked: airplay, itunes, googlecast. Running "show airgroup status" in the shell confirms that these services are enabled.

 

My SSID has broadcast filtering set to "ARP".

 

The Chromecast will appear as an Airgroup server when it is first turned on but it sits idle for 20+ minutes, it disappears as an Airgroup server and never returns again unless I reboot the Chromecast. When it is listed as an airgroup server, everything works great within the VLAN and between VLANs, however, when it isn't listed, it doesn't work at all.

 

I have an Apple Airport Express on the wired network with airplay enabled and it always listed as an Airgroup server and it always works.

 

One difference I noticed between the airplay and googlecast services is the Airgroup cache for the Airport Express is constantly being updated whereas with the Chromecast the cache is never updated.

 

I notice that the IAP doesn't have the "active-wireless-discovery" option for the Airgroup cache, is that because it is always enabled now? Or is it not included in the IAP? It sounds like it might help with my issue.

 

As a side, if I turn off Airgroup, and change my SSID broadcast filtering to disabled, the Chromecast(s) work all the time within the VLAN.

 

Thanks,

Scott.

Scott83,

 

On the commandline of the controller, you should type "show airgroup blocked-service-id" to see if your chromecast is sending service ids that have not been added to the Chromecast service.

Re: Aruba OS 6.4 and Google Chromecast

@Colin

 

There are 7 things listed there, 3 of which reference googlecast.

 

@Tim

 

Is 6.4.3 available for the IAP-205? Other posts I've read seem to indicate that it was still beta for the IAP.

 

Thanks guys,

Scott.

Re: Aruba OS 6.4 and Google Chromecast

Scott,

 

Please use the instructions here:  http://www.arubanetworks.com/techdocs/Instant_41_WebHelp/InstantWebHelp.htm#UG_files/Services/AirGroup/Configuring_AirGroup_on_.htm?Highlight=airgroup to ensure that the Chromecast service is enabled.  If it is, add the 3 lines you see on the blocked service IDs to the ChromeCast Service.  After you add them, make sure they are no longer blocked.  See if that fixes your issue.

Re: Aruba OS 6.4 and Google Chromecast

Hey Colin,

 

Thanks for the instructions but it won't allow me to add the blocked service IDs, they are:

_\037f8012bb2514bb5f7025f4c2741dc003016a32235._sub._googlecast._tcp
_\037b5c891634da02b05588c11e9ebefc2616a1b6193._sub._googlecast._tcp
_\0379e5e7c8f47989526c9bcd95d24084f6f0b27c5ed._sub._googlecast._tcp

 

I can't edit the googlecast service in the UI so from the console I:

 

# config t
(config) # airgroupservice googlecast
(airgroup-service) # id _\037f8012bb2514bb5f7025f4c2741dc003016a32235._sub._googlecast._tcp
(airgroup-service) # id _\037b5c891634da02b05588c11e9ebefc2616a1b6193._sub._googlecast._tcp
(airgroup-service) # id _\0379e5e7c8f47989526c9bcd95d24084f6f0b27c5ed._sub._googlecast._tcp
(airgroup-service) # end
# commit apply
commiting configuration...

could not add this id.
#

 

I tried adding them to a new service called called Chromecast in the UI but it tells me they are invalid. Now I can see why it probably isn't working, it deems those IDs invalid.

 

Thanks,

Scott.

Scott83,

 

EDIT:

 

Scott, Do you have DLNA enabled on the Airgroup Discovery Tab?
