Configuring the minimum version of the TLS protocol

Use the following procedure to configure the minimum version of the TLS protocol.

Earlier releases used a self-signed certificate generated using the OpenSSL API, and this self-signed certificate was installed in /inflash/.ssh. The self-signed certificate is now generated with the Mocana API.

Disable the web server before changing the TLS version. By disabling the web server, other existing users with a connection to the web server are not affected by changing to a different version.

The switch by default supports version TLS 1.2 and above. You can explicitly configure TLS 1.0 and TLS 1.1 version support.

Procedure

  1. In the navigation tree, open the following folders: Configuration > Security > Control Path.
  2. Select General and then select Web tab.
  3. In the TlsMinimumVersion field, select the TLS version you want to configure as the minimum on the system.
