I'm trying to diagnose some connectivity issues at our site (certain clients dropping their wireless connections quite often). We've got a deployment of a cluster of IAP-105s using WPA-Enterprise authentication with a local RADIUS server.
I'm seeing a lot of "WPA Key message 2 from Station <redacted> did not match the replay counter" messages for the clients in question in 'show log security'. Searching for this issue turned up the following page:
https://arubanetworkskb.secure.force.com/pkb/articles/Troubleshooting/R-450
which indicates that increasing the WPA key period might be something to try.
The instructions on that page ("configure t; aaa authentication dot1x test; timer wpa-key-period <time_in_milliseconds>")
are apparently not intended for IAPs, since I can't find anything close to this in the CLI. I also don't see anything like a "WPA key period" in the GUI.
Is it possible to tweak this parameter on an IAP-105 running firmware version 6.2.1.0-3.3.0.0_38115? If so, how?
Thanks,
