When doing debug client (and its been a little while since it was necessary for me last) , Im being spammed to death by :
*DHCP Socket Task: Aug 25 12:28:16.863: [PA] IP Context distribution - event: (DHCP IP LEARN) msCount: 1 ToAllAps: 1
Many many lines of this.
I have tried disabling dhcp messages, packets and so on ... they still keep coming.
Is there any solution ?

Bascially it looks like this : so 2 to 3 lines each second ... its a pain.

Hello,
Please update what is dhcp mode on the wlc?
Global/proxy?
It is only logs or users are facing any issues.?

DHCP mode is ... ehh .. non-proxy if thats what you are asking.
Users are facing issues thats why I wanted to debug client.
But they are not facing DHCP issues.
I think its a reauth / PMK issue something with 9120 and 8.10MR3
On MR2 no problems with 9120, but of course problems with 2800/3800.
On MR3 no problems with 2800/3800 but now problems with 9120.
And I wanted to do some initial debugging to investigate if it was something obvious.
But as I wrote, Im being spammed to death by those lines.
(In between there is the normal client debugs, but I think Im not getting everything, and the WLC seems "slow" and sluggish when i enable debug client because of all those messages Im affraid).

1) Have a sanity check of the controller configuration : https://cway.cisco.com/tools/WirelessAnalyzer/
2) Client debugging can be analyzed with this tool : https://cway.cisco.com/tools/WirelessDebugAnalyzer/
3) Make sure controller software is not too old and or use latest release in a particular train (e.g.)

1 and 2 ) : He he ... yes ... Those are excellent tools, but thats not really the issue.
3: The latest and the greatest 8.10MR3 so ... "Not to old".

- The tools are indeed not the issue but are intended to >assist< ,

Hmmm perhaps. But then it would need to be disabled on all SSID's I guess ?
I will try it , good suggestion.

I really don't know if it will help, but it might be a difference to my setup and an easy thing to try.
