If you are into jWeb, here is how to install a Certificate Authority issued certificate to your JunOS device for jWeb interface.
1. Create a PEM bundle of your CA issued certificate (private key followed by the certificate)
2. Place the certificate on the device filesystem
a. Using the shell, "vi /var/tmp/hostname.domain.tld.pem" b. Using SFTP "scp hostname.domain.tld.pem user@asset.domain.tld:/var/tmp/"
3. Load the certificate in the store :
set security certificates local "hostname" load-key-file /var/tmp/hostname.domain.tld.pem
4. Tell jWeb to use your new certificate :
set system services web-management https local-certificate "hostname"
5. Commit de change
commit comment "add new ssl crt for jweb"
OR if you are running a stack/HA :
commit synchronize comment "add new ssl crt for jweb"
