Good day Matt,
We have a combination of IAP-135 and IAP-125's , we are running a older
firmware (yeah i know it needs updating something for next month or so)
Worst luck I couldnt work out how to modify local arp caches on the access
points.
I have just enabled "Deny inter user bridging" and tha
For those of us with Aruba wireless, www boy, could you share some more
info about your setup/code version/configuration/specific APs/controller
model(s)/etc?

This is a less than helpful feature in a lot of situations…
e.g. I was attempting to work on an IOT device and test OTA firmware updates in
a Hotel a little while ago.
The client isolation on the wifi network resulted in non-obvious failures that
took some time to identify.
In general, people
Turn on client isolation on the access points?

We are running 8.5 and 1815s and I don’t think we are seeing this problem.
We do have a very small number of 1810s and did see some strange behavior but
it doesn’t seem to match this problem description.
Is proxy arp disabled on the default gateway device? That could potentially
interact stra

You asked if anyone else has seen this. It’s possibly going on in other
networks but nobody is noticing. What symptoms brought the problem to your
attention?
You can sanitize the packet captures by limiting them to just the headers. The
payloads are likely not useful for troubleshooting anyway,

I have some packet captures, but as they're from a live network, I'd rather
not post them publicly.

Can you post some packet captures?
I was a network engineer on the WiFi network at SFO, for both passengers and
baggage scanners, with several hundred APs. Several times we were misled by
packet captures that seemed to show client traffic causing network problems,
such as packet storms, but wh
All,
We're seeing a bit of a weird one on our network at the moment, and wondering
if anyone else has seen it.
Since Friday we're seeing Apple devices (we believe it's both laptops and
iPhones) responding to ARP requests for the default gateway IP with their own
MAC address (i.e. ARP spoofing /
