In the last two days I have found one occurrence of com.apple.systemdefault
We run both Meru and Cisco going through Freeradius.
It was coming from a Cisco controller and was a Stop accounting record. I was
unable to find a corresponding Start record yet.
We have not noticed this before, but
If you don't have LAG set up, you get MAC flapping on the switch - check
the log on the switch perhaps. I'd have to check the manual, but from
what I recall, it's required. I've run multiple 5508s and WiSMs, but
always did LAG.

We have seen this to varying degrees, off and on since early 2006 code. The one
TAC case I did open a while back focused on AP switchport configs, spanning
tree, CDP, and stuff like that. Wasn't particularly conclusive, and we have
always used LAGs to our controllers whether they are WiSM or
TAC was quick to suspect LAG as well but our settings were already
at the recommended when I opened the case.
Just to rule it out, I dropped one of our controllers from an 8 port
channel down to 1. Unfortunately we still see the drops at the same
rate.
Interesting theory. We do use DHCP, although we're using DHCP across
the entire campus so if this was the case, I would think we'd see more
of it, not just in the dense student areas.

Good to know.
The trunks are actually all 10Gig links, or 90% of them are, so
utilization is most likely not the case, which I'm able to verify from
Cacti graphs. The APs are connected to 3560Xs PoE switches that then
uplink into either a 3560E-12D or directly into a 4900M where the 5508s
Dan,
Do your admin ap's also connect to 3560 switches or another model? I know
you mentioned that the uptime was good but the capwap session was
restarted. I've read that when enough power isn't given that certain
features may not work correctly, may want to look in that direction as it
seems
How large are your wireless subnets? Are you doing any broadcast/multicast

You might also check for laptop loops -- anything with wired and wireless

I think you have some of us all getting curious! ;-)
Could you put a historically stable admin AP onto the 5508 and vice-versa to
see if behaviors change?
Do we assume that all switchports in the path are showing they're running
clean?
Any QoS config in place on the switches?

Craig,
Interesting. The admin APs are connected to a wide variety of 3550/3560
models. A good number of them use power injectors due to one department
at a time wanting wireless in their area. When we've done larger
projects we'll use PoE.
I'm somewhat familiar with the power limiting
Dan,
That is correct, it usually limits the power to the radio but I'll see if I
can find the doc about what I mentioned. I'd assume that most or some of
your admin ap's are NOT 3502's as you are running 3550 switches and they
don't support the recommended power. Did you happen to enable data

Yes. We're all-Apple here and saw those showing up. Never got to the bottom

Last year there was some discussion on this list as per setting up Wifi on
Inter-Campus shuttle buses and here at McGill we were in the middle of doing
our tests for our 4 shuttle buses between our downtown and remote campus.
As of January this year, we now have Wifi on all four of the buses.
This what we see on the AP at the time the AP disjoins:
*Feb 1 14:16:25.174: %DTLS-5-SEND_ALERT: Send FATAL : Close notify
Alert to 10.246.207.214:5246

disabled.
*Feb 1 14:16:25.227: %CAPWAP-5-CHANGED: CAPWAP changed state
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
This sounds fun. On our end, we found that the bus provider wasn't real

What about leveraging the USB port on the modem, for the likes of the

My first instinct would be to try to do this with old iphones. They have GPS
and WiFi. It would be easy enough to wire them to 12v with a cigarette lighter
charger. And if none of the apps on the appstore will work for tracking, it
shouldn't be too hard to roll your own.
B.
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.

What time is your controller showing? From your log messages it looks like
its 2:16pm there? AP's have issues when the time is off between the
controller and the ap's.

DAI?
I have some bad experiences with DAI and some crappy low end printers. (to
the point where they go in they're own VLAN without DAI) (And some very
expensive video conferencing units)
My switch vendor also had a bug with DAI (over 2 years ago now) that got

Do you have the APs in public subnets or private subnets? Occasionally we see
this problem happening in our environment as well. Currently we put APs in
public subnets. I worked with Cisco TAC on this and we could not find anything.
Finally TAC suggested we move APs to private subnets and
Private management space has not helped us at all. If there is no reason given
for the suggestion that you move to private space, it sounds like straws are
being grasped at.
We have been on private space for quite while for AP management, switch

Anyone have 40 to 50 Cisco AP power adapters for Cisco 1131 Access points
they don't want. The AP shipped with the AIR-PWR-A, which has been

I love that idea, but does that work in reverse? If someone accidentally uses
