Configuring the TLS version for WebLM

Last Updated : Oct 31, 2022 |

About this task

WebLM supports the following TLS versions:

  • TLSv1.3

    From Release 10.1.2, WebLM supports TLS version 1.3.

  • TLSv1.2

  • TLSv1.1

  • TLSv1.0

When you deploy WebLM, by default, WebLM is set up with minimum TLS version 1.2.

Note:

  • WebLM does not preserve the minimum TLS version setting and cipher suite setting during the Backup and Restore operations.

  • WebLM does not retain the TLS version value after upgrading from earlier release to Release 10.1.2 and later.

Procedure

Do one of the following:

  • To configure minimum TLS version 1.3, type the command: configureTLS -ENABLE_TLS_VERSIONS TLSv1.3

  • To configure TLS version 1.2 and above, type the command: configureTLS -ENABLE_TLS_VERSIONS TLSv1.2

  • To configure TLS version 1.1 and above, type the command: configureTLS -ENABLE_TLS_VERSIONS TLSv1.1

  • To configure TLS version 1.0 and above, type the command: configureTLS -ENABLE_TLS_VERSIONS TLSv1.0

If you set the TLS version 1.0 or TLS version 1.1, WebLM displays the following message:

Warning! You are setting Minimum TLS Version to TLSv1.0 or TLSv1.1.
For increased security, it is recommended to set Minimum TLS Version to TLSv1.2 or higher, if these protocol levels can be supported in your configuration.

Are you sure you want to proceed with selected TLS Version? [y/N]
  1. At the prompt, type y to proceed.

WebLM enables the required TLS version.

For example, when you enable the TLSv1.3, WebLM displays the following message:

Enabling TLSv1.3
Stopping WebLM server
Staring WebLM server
Enabling TLSv1.3 completed successfully
