Use an HTTP session to download and install an SSL
security certificate file on the switch
Note: You are not required to obtain an SSL certificate. The security warning
that might display in your browser prompts you to confirm that the
self-signed certificate of the switch is valid. Once you do so, the
browser warning might no longer display when you log in.
If you obtain an SSL security certificate from a certificate authority, you can download and
install the SSL security certificate through an HTTP session using your web browser
.
For an SSL security certificate, you must download two Privacy Enhanced Mail (PEM) files to
the switch:
• SSL Trusted Root Certificate PEM file. This the certificate file, which must be in the
format xxxxCERTxxxxx.pem.
• SSL Server Certificate PEM file.
This is the key file, which must be in the format
xxxxKEYxxxxx.pem.
Before you can download and install an SSL security certificate, you must disable HTTPS on
the switch.
