It bothers me greatly that this OS and these controllers are supposed to also figure into the fabric/DNA story. Compounding current problems- which I know I’ve been putting up with since 2006- with the whole automation thing just sounds like a less than stellar strategy.

It doesn’t fix all issues but can at least pre-identify and allow you to manually sort before it becomes an issue. I’ve only just started playing with it. We’ll see if we have any failures at upgrade. We’ve been having a few 2702i’s go down recently while faulty cables are replaced. It’s called wlanpoller, does plenty of other things but since we are doing an upgrade shortly I’ve just started with that. You can ask for it from TAC I got info about this while at Cisco Live Melbourne this year. https://www.ciscolive.com/global/on-demand-library/ Look for “Troubleshooting WLANs - Automating Log Collection and Analysis - BRKEWN-3671” -- Jason Cook Information Technology and Digital Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 CRICOS Provider Number 00123M ----------------------------------------------------------- This email message is intended only for the addressee(s) and contains information which may be confidential and/or copyright.

We'd prefer to only do this once more if we can (i.e. to get away from the flash corruption bug).

We rebooted one AP yesterday and the customer tells us that their connectivity improved. In another instance, we rebooted an AP and the situation did not improve (in fact, we replaced it - still to no avail). We have over 1800 of these deployed so the impact is widespread. All in local mode. I would be very keen to hear if anyone else would be willing to share TAC case details for any tickets logged to Cisco for this issue.

Replication could be challenging, we have 27x 702w’s currently but I’ve only come across 1 confirmed repeat offender. Though some of those are in student accommodation, so I suspect a few of the complaints there could be related. However getting details to troubleshoot are somewhat more challenging there. Anyone worked with TAC or had a bug outside of what Stephen mentioned? I don’t recall seeing those logs when looking at this one. Haven’t been in contact with TAC due to low use/impact vs other work. -- Jason Cook Information Technology and Digital Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 CRICOS Provider Number 00123M ----------------------------------------------------------- This email message is intended only for the addressee(s) and contains information which may be confidential and/or copyright.
