Usage guidelines
To enhance system security, you can disable the SSL server from using specific SSL protocol
versions (SSL 3.0, TLS 1.0, and TLS 1.1) for session negotiation.
Disabling an SSL protocol version does not affect the availability of earlier SSL protocol versions. For
example, if you execute the
ssl version tls1.1 disable
command, TLS 1.1 is disabled but TLS 1.0 is
still available for the SSL server.
