wsma issues configuring catalyst 9300 48P

[amalitol81]

Hello everybody,

I have configured for the first time switches catalyst 9300, but something weird happened to me. I just manually applied all the basic configurations (never configured wsma values), but for some reasons few of the catalyst 9300 didn't get the default wsma configuration. as you can see in the sh run command. The only difference between the ones that were well configured and the others that didn't get the default wsma configuration is that the last ones has an line aux 0 (that I can not see in the physical switch).

When I try to open an HTTPS windows to access the SW it just appear the following message:

nil response from WSMA

Is there a way to fix this wsma problem ?

Thanks in advance.

########## wsma default [without wsma configuration (see line aux 0)] #######

Hello community,

I found a solution.

It seems there is a bug in IOS-XE version 16.6.1 were wsma (web-server) do not work if only is active the https, and http no. If you want https works, you need to enable http also using (config)# ip http server along to https. Otherwise, https will show 'nil response from wsma' in the browser.

However aux 0 is still there. Maybe the best solution is to update the IOS-XE to version 16.6.2.

SWs were updated to version 16.6.2 and now everything is functioning fine.
