FRA requires a close look at your existing configuration. To be the most
effective, you must have your RRM run interval back to default so that it’s
collecting information more often, and with shorter time gaps. If you’ve upped
those defaults you can wind up with FRA making a decision with very
As a quick point of reference, the next version of 8.2 code up from the one
you're running (8.2.151.0) implements TKIP on the AP3800s (all wave 2
platforms from Cisco) as well as resolves numerous outstanding issues. Full
release notes are over at:

I have deployed few 3800s for testing before rolling them out throughout the
campus.
Only issue I saw was that they don't support "tkip" so have to only enable
"AES" as WPA2 encryption. I haven't come across any further issues. I am
running code 8.2.141.0 on WLCs.

Hi folks,
My understanding is that a 3800 is a 2800 with a module slot, so the real
decider is "Are you going to deploy any modules?".
Happy, as ever, to be corrected.

Hi Bryan
have you read this Miercom report ?
http://miercom.com/pdf/reports/20151120.pdf
It compares 1832, 1852 and 3702 which might help you figure out
if you really need 3800s.
In mot cases 1850 and 2800 should be enough.
best regards,

environment. Similar to RRM, it's a tool but fallible so we don't trust
full-out automatic mode.

No we did not go to that detail. I assume they meant a typical
classroom/lecture hall scenario. Do you use FRA in your deployments, Lee?

Hi Dennis,
Did Cisco give a sense of how they would define High Density for the flex radio
applicability?

We have 300+ 2802 APs. We notice sometimes FRA(Flexible Radio Assignment)
disables the 2.4Ghz radios when it shouldn't and cause coverage issue. Has
anyone notice this issue as well? I consulted with Cisco and they say the best
use for FRA is high density scenario. It may cause issues where you
We are currently deploying 1800, 2800 and 3800 series and we are happy with the
results with one caveat: We identified a bug where RX-SOP is supposed to be
supported but it is not working at this time. Bug ID is CSCvf05427. It might
not be available on the web site until some time next week.

I also didn’t see the need for 3800s over 2800s. We started deploying 2800s
last month, having upgraded software to 8.2.151.0 ahead of time. No complaints,
granted it is summer and they haven’t been used much yet.
Some of the 2800s are replacing 3700s in a gym so we can take advantage of the

The code reliability is pretty good now. We're running 8.3.121.0 (for the RTLS
capability) with ~300 3800 series APs. A couple of lessons learned:
1- Make sure your AP MSS is adjusted (1363 to 1250 in our case) or you'll see
slow (like 2Mbps down) speeds on some devices with these APs but not
Hi Bryan,
This doesn’t answer your question, but I thought I’d mention that we ended up
going with the 2800 series APs instead of the 3800s. Historically we’ve stayed
in the 3000 series but for the differences between the 2800 and 3800, we
thought the 2800 was enough for our environment.

Bryan,
We have been using 3800s for about a year and we do use Prime to manage them.
The only issues we have had was their power consumption requirements. They
require more power over POE than our 3750E and 4500E could provide. We are now
rolling them out in conjunction with our switch upgra
There were issues at FCS (first customer ship), but they’ve been trouble-free
for me on 8.2 MR4 and now MR5. On a side note, client performance on the 3800’s
is significantly better than the 3700’s, especially when coupled with multigig
switches.

Couldn't find a recent discussion on the list archives, so I'll ask my question.
For those of you that have Cisco 3800 series APs in production, how have they
been working for you recently?
We currently purchase 3700 series APs as our standard for new installs and
replacement of our 3500 series
We do not use EDUROAM.
We configure our current PEAP-MSCHAPv2 clients to trust the certificate chain
and a specific server name in the certificate. We can update the server
certificate so long as the certificate chain is the same.
