Hi Scott,
No such use cases present, I am just wondering what would be the effect on that procedure on the CAPWAP APs, will it benefit the switch by gaining less CPU utilization since MAC addresses of clients are not learned by the switch itself rather it is tunneled to the WLC.

On our case we hit this bugCSCve57121 ( https://bst.cloudapps.cisco.com/bugsearch/bug/CSCve57121/?reffering_site=dumpcr ) and TAC recommended us to upgrade to 8.3.133.0 MR. So far no more disconnections experienced by user.

Hi, As we all know, capwap tunnel is built from lightweight AP to WLC on a Unified WLAN. What are your thoughts when you disable the mac learning on the switch example on the management VLAN of AP?
TIA!

Hi Scott,
what firmware were you using on your WLC?
Also encountered this issue, users are complaining because they don't want to connect and disconnect to the SSID once they are dropped. Temporary fix is changing the 2802i AP to 2600/3700 AP.

Hi,
Does Cisco WLC have an option to configure an XML API Server or equivalent command in CLI just to configure an XML API Server? I could not find any related documentations.
Thanks!

Thanks Leo, Salamat ng marami
Indeed TAC has recommended that, herewith below is his email:
"After checking on my I found that we had a bug with same symptoms (now it’s closed since the issue is not reproducible on the latest 8.2 release) https://tools.cisco.com/bugsearch/bug/CSCuy97681/
So can you please upgrade your WLC to the following recommended release 8.2.130.0: https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-TAC-Recommended-AireOS.html?cachemode=refresh#anc8"
I have asked TAC your reply on this thread. Thank you so much,

Hi guys,
I am just wondering, no client is connected on 5GHz and yet there is a very high channel utilization with 0% interference. Do you know how is that possible? no problem on 2.4GHz. Im using Cisco WLC 5520 and firmware version 8.2. Is this some kind of bug?
My troubleshooting procedure on that is restart the AP and the channel utilization returns to normal. Please see attached photo.
Thank you for the help,
JE

Hi guys,
Given: 5520 WLC, high density access points, concrete walls. 1832 APs.
TPC Version
Coverage Optimal Mode (TPCv1)
Power Level Assignment Mode
Automatic
Maximum Power Level Assignment (-10 to 30 dBm)
30
Minimum Power Level Assignment (-10 to 30 dBm)
-10
Power Threshold (-80 to -50dBm)
-70
Is it okay to statically configured the power level of the APs to custom level 1 instead of using RRM (which normally gives 7* or 8*)?
Or should i adjust the configuration of minimum and maximum power level?
Does hysteresis also needs to be changed?
Regards,
JE

Yes you are correct, it is client's final decision. I am just wondering why my wifi signal suddenly goes down from full bar to 1-2 bars when at first, I am connected to Cisco AP. Does interference and other RF factors has something to do with that phenomenon? Take note that the Cisco AP is place on top my client device and the other AP is non-Cisco.
