HiSo this morning we upgraded one of our Cisco 9800-CL clusters from 17.3.5a to 17.3.6.All C9115AXI-B APs (14) on a certain site did not join after the upgrade.The pre-download went fine, but when I finally got a console to one of the missing APs it ...

Hi We're running multiple Catalyst 9800-CL controllers (17.3.3)Typically one cluster in North-America will be backup for the APs attached to a controller in South-America.I have run the config files through the Wireless Config Analyzer, and I find it...

HiWell, the "BAD_ADDRESS situation" is a classic when it comes to Cisco Wireless Controllers.We're also seeing this on the Catalyst 9800 platform. On the 550x platform we could issue the command “config ap dhcp release-override” to solve the problem....

Hi SurendraI don't have a SR opened for this.Cisco TAC showed no interest in helping out when I reached out to them via the Cisco TAC chat function.There is a text file in this community post that shows the failing u-boot process from one of the APs....

Yes, we have already done that.We have also configured a new WLC on 17.3.5b, and we will test to migrate a C9115AXI AP to this test WLC - before we upgrade all our main WLCs.

Started a new chat with TAC today. Explained the situation and pointed to this thread.Told that our company probably were beyond help at this point, but that they should investigate this problem thoroughly.TAC Answer: You have no contract....You can ...

HiI just used the TAC on the web-page, the chat function.So I'm not sure where they were located.I totally agree that it doesn't make sense to RMA the AP when it's clearly a bug in the 17.3.6 code.Frustrating "exercise". Now we have to connect to eac...
