Aruba UXI Packet Capture Issue

One of the key features I hoped to make use of in the Aruba UXI sensor (formerly Cape Networks) is remote packet capture. This is performed on the sensor status page as shown below:

The problem is that it doesn't produce a file that is readable in Wireshark, with most of the 802.11 frames marked as malformed.

After raising this issue with Aruba support they came back with a response after over two weeks to say that this is a bug:
"The sensor do not capture the full packet off the wire, the snap length is 2048 bytes at the moment including the Radiotap headers, which means that sometimes wireshark won't be able to fully parse the packets.
The backend team is still working on the this."

Considering that the last update to the UXI sensor was on Aug 2019 it is a bit concerning that they either haven't noticed this issue or that they can't fix it. I can't help getting the feeling that the development of this product is on the Aruba back burner now.

Captive Portal Testing on Aruba UXI

The Aruba UXI (formerly Cape Networks) sensor is a useful piece of kit to help understand the status of a wireless network remotely and from the perspective of an end user. We have it set to test connectivity to our 802.1X Wi-Fi using some different credentials to check the function of different roles. However, one network that was missing was our guest network.
The guest network, in common with many UK universities is provided by the Cloud from Sky and is protected by a captive portal. I had always assumed that this would be a blocker for the UXI sensor but it turns out that they have a way to around this. Once an a guest account has been created then using a chrome plugin called "Aruba Recorder" if we perform the manual login and provide the output to Cape Networks support they can add this to the sensor and it will perform the user login. The full details can be found here.
Unfortunately at this time it isn't possible for the user to upload the recorder output but requires the Cape support to do this. Hopefully this won't always be the case.
