Hello
I was a bit confused about the traffic ports used by mobility on WLC AireOS or IOS-XE.
Trying a quick review of traffic ports used by mobility :
I also found this matrix : https://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/113344-cuwn-ppm.html#toc-hId--1639616132
About CAPWAPP between APs and controllers, it seems limited to UDP 5246 and UDP 5247 (encrypted).
But why this documentation from AireOS 8.10 states that if using secure mobility, we need UDP 5246-5247 ports ? I tough it was limited to CAPWAPP between controlers and APs :
I edited this post on March 16th to add details. Am I wrong ?

I think that's probably a mistake. Use the feedback option to report it. Sometimes, eventually, the document will be corrected. If you're lucky it can even happen within 2 weeks.

Hi
I had a feedback. The documentation has been fixed. Now it states :
"UDP port 5246 and 5247 are for CAPWAP between AP and controller. Encrypted mobility uses UDP 16666 for control and UDP 16667 for data (either encrypted or plain). EoIP IP 97 is for old mobility."
