We are deploying a large number of IV pumps with internal wireless NICs( dlink)
Clients can successfuly authenticate...then re-authenticate every few seconds..
controller code 6.0.188
ACS version 4.2
authenticating to microsoft AD
Clients are configured for WPA2, PEAP, MSCHAPv2,
each has a unique identity/password
ACS is the CA( using self signed cert)
Any know of a timer value or setting that my trigger this ?

Charles,
Just a thought on this, is WPA AES enabeld on the SSID? If so try disabling it if you can. I have run into several instances where when that was enabled even though not being used it caused thousands of re-authentications per second. I actually saw it take down 2 seperate client facilities, in both cases I had TAC Cases open and TAC couldn't understand why it was happening, only that once we disabled WPA AES it immediately stopped and the clients only re-authed on the timer set in the WLC for Session timeout.
Hope this helps.. Please rate useful posts.
Thanks,
Kayle

for starters, do a client debug and see what is going on ...
from the WLC
debug client XXXXXXXXXX
