Self signed certificate expiration for HTTPS

Eric_Burke — Sun, 03 Jun 2018 19:39:00 GMT

Good morning! Using a self-signed cert for use with HTTPS and noticed that the expiration is automatically 1 year from the date of creation. Does anyone know if there is a way to change the expiration date to something longer (maybe 5 years)? Here's what I'm using:

conf ssl certificate privkeylen 2048 country US organization "Our Company Name" common-name w-core-sw2.company.local

Thanks,
Eric

Eric,
You can't from the self sighed feature on the switch. You can add your own cert you generate on your PC.

Thanks Stephen. So what are you actually doing when you enter the ssl cert info as I noted?

You are having the switch generate a key. You can generate your own in ubuntu, and upload it to the switch.

Ubuntu:~$sudo openssl req -x509 -nodes -days 1825 -newkey rsa:2048 -keyout ./private.key -out ./public.crt

Then login to the switch and enter the keys:
