TLS support

By default, all TLS versions such as TLS 1.0, TLS 1.1, and TLS 1.2 are supported on devices that act as an HTTP server.

For devices that act as the SSL client or the syslog, OpenFlow, RADIUS, or secure AAA client, the TLS version is decided based on the server support.

You can configure the minimum TLS version on FastIron devices using the ip ssl min-version command. The TLS version configured as the minimum version and all the later versions are supported to establish the connection. For example, if TLS 1.1 version is configured as the minimum version, both TLS 1.1 and TLS 1.2 versions are supported. For devices that act as an SSL server or HTTPS server, the default connection is with TLS1.2.

You can use the show ip ssl command to identify the TLS version that is configured on the device.

For TLS support of RADIUS, the RADIUS server checks the certificate to make sure that the user connecting for authentication is not being intercepted. The RADIUS server then determines that the server and client are using the same encryption types. Then the RADIUS server and device send each other unique codes to use when encrypting the data traffic.
