Chromebook P2P updating

[s.hellman]

We have about 9000 chromebooks, and when they downloads released updates they chokes the internet connection.

Google documents states thata chromebook first tries P2P to other chromebooks to get updates, and if that failes they fetch it from googles update servers.

Obviously P2P between our chromebooks does not work, what should I look at on the controllers to get it working?

Hello @s.hellman

 You can enable it at WLAN level. Click on the WLAN ID where devices is connected, then go to the Advanced Tab and enable P2P. You will this as "P2P Blocking Action" and this is "Disable" status. Just change it to "Enable"

-If I helped you somehow, please, rate it as useful.-

"P2P Blocking Action" has three alternatives, Disable / Drop / Forward-UpStream

Cisco documentation says this:

Disabled—Disables peer-to-peer blocking and bridges traffic locally within the controller whenever possible. This is the default value

Drop—Causes the controller to discard the packets

Forward-UpStream—Causes the packets to be forwarded on the upstream VLAN. The device above the controller decides what action to take regarding the packets

We have it set to Disabled wich should enable P2P.

My bad, you are correct. On this case, WLC is not blocking P2P.

It looks like I only had to enable mDNS to get it to work.
