I’ve been waiting on an engineering fix to help with the Kernel Panic on the 1810’s, however I received an e-mail from Cisco last week that they found bugs in MR5 and it wasn’t recommended that we use it. We’re running dual 8540’s/HA
I have Rlan’s, Flexconnect and building groups configured, so it may just be due to what we’re doing with our AP’s, but the only version of code that we can keep the Rlan’s up (reliably) is with 8.2.130.0. Upgraded to 8.2.141.0 and everything went down when using Flexconnect/Rlan combination. I’m waiting to hear from Cisco about when the code after MR5 is to be released and test it. *From:* The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto: [email protected]] *On Behalf Of *Powers, Timothy Charles *Sent:* Thursday, March 16, 2017 11:51 AM *To:* [email protected] *Subject:* Re: [WIRELESS-LAN] Cisco WLC code recommendations We’ve had clean air sensor crashing on 2802I’s. 8540 controllers on 8.2.141.

A “Kernel Panic”. AP loses its mind. Very prevalent on the new stuff, to a much lesser degree affects “older” stuff. Sometimes the reset fixes it. Sometimes not. We doubled down on 1810’s and 2802’s. Bugs galore. Which are actively being fixed-to be fair. We are running on engineering code and HUGE improvements have been made. Soon, I think/hope, it will be rock solid.

We also run a half dozen 5520s with 8.2.141.0 and they have been running solid with around 1k APs each and upwards of 10k clients. We do not however run anything but 2600, 3600, 2700 and 3700 APs. The only issue I have seen that I don’t understand well yet is related to some APs losing the minds during network interruptions. The APs will appear up from CDP neighbor information, but will have lost their name and will not connect to their configured primary or secondary controllers. A power cycle will often recover the AP, but not always. I believe that issue started with 8.2. Thank you.
