Hi Salil, 

I just reviewed, briefly, the list of fixed caveats and is CSCvi20869 included in any way?

Hello Leo,


I will include the fix in the next refresh.


regards, Salil

Thanks, Salil.

Sorry to be a pain, Salil.  How about CSCva34879?

Hello Leo,


that bug is in U state (un-reproducible). So no fix .


regards, Salil

Thanks, Salil.

Will you update this thread once a new build has been posted to the file share?

Yes will do

Just wondering, for the WLC 3504 it's the file AS_3500_8_......aes?

The release notes don't tell and there is no readme file.

Just tested it, it's indeed the correct file. Upgrade worked, but I found some new, never seen, boot messages, once my single test AP connected:

5	Mon Apr 23 09:08:17 2018	AP's Interface:0(802.11b) Operation State Up: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Reset while setting promiscous mode serving channel. Status:NA
6	Mon Apr 23 09:08:17 2018	AP's Interface:0(802.11b) Operation State Down: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Reset while setting promiscous mode serving channel. Status:NA
7	Mon Apr 23 09:08:17 2018	AP's Interface:1(802.11a) Operation State Up: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Reset while setting promiscous mode serving channel. Status:NA
8	Mon Apr 23 09:08:17 2018	AP's Interface:1(802.11a) Operation State Down: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Reset while setting promiscous mode serving channel. Status:NA
9	Mon Apr 23 09:08:14 2018	AP's Interface:1(802.11a) Operation State Up: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Unknown Reset Status:NA
10	Mon Apr 23 09:08:14 2018	WIPS Alert: Reason "NoProfile" detected on AP MAC: 6c:50:4d:ab:0b:00, AP Name: 3502AGN-5U17-1
11	Mon Apr 23 09:08:14 2018	AP's Interface:0(802.11b) Operation State Up: Base Radio MAC:6c:50:4d:ab:0b:00 Cause=Unknown Reset Status:NA

Never seen the first four messages of those before. I don't remember enabling promiscuous mode before (also the error message has a typo in promiscuous).


Brian Taylor

Which file for 2504 wlc?

Hello Brian,


regards, Salil
VIP Advisor

Just discovered that this release misses a dot in the filename of this forum post. Because of that it can't be found with 8.5mr3.
@Salil Prabhu could you maybe edit the title of your main post to include a dot between 8 and 5? :) That way it would have the same naming scheme like the other beta releases.

Sorry for the error.. I will hold the current link as the link has been circulating around and adding a . will append to the URL and many folks may see it not available any more.. But feedback ack'd
