Cisco Switch Web UI with HTTPS (lock icon)?

H3lpAppr3ciated
Level 1
Level 1

Hello, has anyone successfully implemented HTTPS on their switch web management UI? I would like to get rid of the warning when I access the web UI, but I cannot seem to find resources about it online.

I am currently using a Catalyst 9300 in my network, connected to a 2900 series router in my current testing environment. After testing, the switch will be connected to a Fortinet firewall instead of the router.

I would like to avoid third-party CAs, and my network does not have an internal CA.

If what I have in mind is simply impossible, I am also open to any other suggestions. If there are any other questions, I'll be happy to answer them.

Thanks, much appreciated!

P.S.: Does configuring a Trustpoint have anything to do with what I am trying to achieve?

Hello,

can you post a screenshot of the warning, as well as the running configuration of your 9300 ?

Hello,

Apologies for the delayed reply. Here is a screenshot of the error I get and the running config of my switch.

FYI: I use the IP address of VLAN1 to access the web UI.

If there are any other things required, please let me know. Thanks
