ArubaOS/InstantOS DCA Problem??

Hey Everyone!

This is my first post in the community.  I was previously a Cisco wireless engineer however I now work with the Aruba platform...  Back when I was working with the Cisco WLC solution I identified a couple of bugs where when DCA was triggered the 3800 series APs would reload, this was of course a major issue as they provided coverage for a crucial area of my building. Now... I was experiencing some massive packet drop issues in one of my Aruba sites which was determined to be aesthetic until it impacts connectivity of users - I don't like that answer but that's not the point.  I was told by a TAC engineer that its possible the packet loss could be due to DCA because when a DCA event is triggered on Aruba APs it not only resets BOTH radios, but will also reboot the access point completely.  This can't be correct - right?  If this is correct it seems like a massive flaw in design.  Can anyone weigh in on this?  I can't seem to find any good documentation regarding Aruba and how it handles DCA/UNII-2 Extended channel ranges.

What is DCA?


When Aruba access points change channel it does not reboot and the radios are not reset.
