Tutorial: Select the SSL and TLS Levels on the Web Server⁠

Sign in to the Admin Web UI.

Select Configuration → TLS Settings.

Scroll down to TLS options for Web Server.

Select your desired protocol version (the default is TLS 1.2).

Select Save Settings and Update Running Server.

Connect to the console and get root privileges.

List the current TLS level:

sacli ConfigQuery | grep -i "cs.tls_version_min"

• If nothing is displayed, the cs.tls_version_min configuration key uses the default value. See the defaults table above for the default value that applies to your installation.

Set the minimum TLS version. Valid values are 1.0, 1.1, 1.2, and 1.3:

sacli --key "cs.tls_version_min" --value "1.2" ConfigPut
sacli start

To reset the minimum TLS level to default, delete the configuration keys:

sacli --key "cs.tls_version_min" ConfigDel
sacli --key "ssl_api.tls_version_min" ConfigDel
sacli start
