9800-CL AWS Configuration Issue

ritchie65 — Mon, 17 Apr 2023 08:56:32 GMT

I have a 9800-CL in AWS which is reachable via GUI and CLI.

When I try to add a WLAN, it wil not accept any WLAN number and the security tab is completely blank with no options at all.

I don't believe this to be a licensing issue as the licennses are per AP, as I understand it.

Could there be some missing/required config to be completed bbefore a WLAN can be added?

Thanks

- Review the current configuration which you have already with the CLI command : show tech wireless , have the output reviewed by : https://cway.cisco.com/wireless-config-analyzer/
Checkout all advisories (for starters!)

Thanks for the info.

The software version we have to use with this AWS implementation is 17.3.4c as that is the only one available that will support the existing 3700 series APs we have to migrate over (pending these APs being replaced with 9000 series)

Is external communication with Cisco (For the CSLU) mandatory to enable the WLC to be configured correctly? I ask because we currently cannot ping/trace to external addresses (8.8.8.8, cisco.com, google.com)

Thannks again

Not exactly in 17.9.3 that support was introduced again because of many customers still having these access points : https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-9/release-notes/rn-17-9-9800.html#whats-new-1793 , it's probably advisable to for that version.

- I don't think so , did you already try the WirelessAnalyzer procedure on on your configuration attempts , as mentioned in my initial reply ?

I have not tried the 9800-CL in AWS, but in Azure, if you don't use the correct server type, you run into issue like what you have seen. Since this is a new setup, you might as well delete that instance and create a new instance following the guide and recommendations. Even though you might of followed it in the first place, doesn't mean something happened. It doesn't take long to spin up a new one and test again. You don't need any license to use the 9800 and that will not affect what you see in the GUI/CLI.
