Specify the accepted SSL protocol version.

Options

  • all—Accept all versions of TLS. This is enabled by default.

  • all-secure—Accepts only secure TLS versions (TLS 1.2 and TLS 1.3).

  • TLS version 1.2 —Accept TLS version 1.2. This enhanced version of TLS provides improved flexibility for negotiation of cryptographic algorithms.

  • TLS version 1.3 —Accept TLS version 1.3. This enhanced version of TLS provides improved security and better performance.

    Note: Starting in Junos OS Release 26.2R1, TLS 1.0 and TLS 1.1 protocol versions are deprecated for SSL proxy—rather than immediately removed—to provide backward compatibility and a chance to bring your configuration into compliance with the new configuration.
