thanks for the info

Are CSCvo05093 & CSCvo04251 going to be included?

Re: 88MR2 Interim Build Availability

Sudhagar Singh — Mon, 11 Feb 2019 11:29:46 GMT

Both are fixed already.
CSCvo05093 - Will be part of the next interim refresh.
CSCvo04251 - Will be part of the future interim refresh.

Can you confirm that AS_7500_8_8_114_108.aes will work on the 5520 series WLC's?

Re: 88MR2 Interim Build Availability

Scott Fella — Wed, 13 Feb 2019 03:11:45 GMT

That is the correct image to use on the 5520

If CSCvo05093 isn't included in 8.8MR2 release then I'll need to regularly reboot the controller (every 10 days).

CSCvo04251 is important because if this doesn't get fixed in 8.8MR2 there is no way I can perform a client debug because my entire screen gets spammed.

Both of the bugs were not present in 8.5.135.0.

CSCvi82746 finally fixed 🙂
Time to test this.

Anybody else unable to SSH into the WLC 3504 since upgrading to this build?
I've tested SecureCRT 8.1.4 (which always worked before) which always had worked until now. It does work if I use a Debian based SSH client.

Re: 88MR2 Interim Build Availability

patoberli — Thu, 07 Mar 2019 09:42:35 GMT

Just checked those two bugs, they are now marked as fixed in 8.8.114.x.

Just upgraded my SSH client to the latest version, still the same issue.

My system was previously on version 8.8.110.61. But the upgrade to 8.8.114.132 doesn't work, it still shows that I am on version 8.8.110.61. Tried multiple times to upgrade through TFTP, never worked.

Can you try to upgrade through HTTP in the Webbrowser? Or do you get any error message when upgrading?

Was able to solve it in SecureCRT.
I had to edit the Session Options -> Connection -> SSH2 -> Advanced and disable here the option "Enable SSH Agent forwarding". After I disabled this it started to work correctly again.
