Serial Port Profiles
SSL/TLS Settings Tab Field Descriptions
You can create an encrypted connection using SSL/TLS for any serial port profile that accesses the
IOLAN from the network. When you enable this feature, it will automatically use the global
SSL/TLS settings (configured on
Security
,
SSL/TLS
), although you can configure unique SSL/TLS
settings for the serial port.
When configuring SSL/TLS, the following configuration options are available:
z
You can set up the IOLAN to act as an SSL/TLS client or server.
z
There is an extensive selection of SSL/TLS ciphers that you can configure for your SSL/TLS
connection; see
Appendix B, SSL/TLS Ciphers on page 347
for a list of SSL/TLS ciphers.
z
You can enable peer certificate validation, for which you must supply the validation criteria that
was used when creating the peer certificate (this is case sensitive, so keep that in mind when
enabling and configuring this option).
Configure the following parameters:
