Stupid it may be as a question, but are your two (or more) DHCP servers handing 
out the same length leases?
You may also need to tweak the DAI settings. I know we had to change the 
default thresholds when we first deployed it.

Subject: Re: [WIRELESS-LAN] Cisco APs losing CAPWAP session

Ok, thanks for validating.  It also seemed a bit strange to me and yes, I 
checked a bunch APs that haven't dropped recently and they all showed 10-12ms.

One thing that occurred to me is we are doing DHCP snooping and Dynamic Arp 
Inspection on the 3560Xs.  That is unique to this part of campus as we haven't 
yet rolled that out to the entire admin side.

Thanks,

It's been awhile since I've read these, but If I interpret this correctly,  It 
took 1m 15s for the AP to associate to the controller.  That's a very long 
time.   Mine usually have association in the 10-20 second range.

Not sure what that indicates, but it's an anomaly from my point of view.

I don't think it's a rouge herring.  (See Backhoe joke from earlier in the 
thread)
