Hi Gertjan, A tac engineer today confirmed with BU that the fix is not even in 8.5.161.5.
I was told to wait for 8.10mr3 which supposedly has a fix for this bug. We can’t go above 8.5 because of presence of old Aps (3500, 3600) so we are stuck 😐. We have another pair of 8540 and I plan to upgrade it to 8.10mr3 and then migrate all 3800’s to it. Hopefully that will fix the issue for us. - Cheers, Kind regards, Tariq Adnan | Senior Network Engineer ICT, Campus Network Services From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Scharloo, Gertjan Sent: Friday, 26 June 2020 10:47 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco WLC Stable code in 8.5 train Hi all, We have some serious issues with 8.5.161.x .
