Description

The security config modify command modifies the existing cluster-wide security configuration.

  • If you enable the FIPS-compliant mode (prior to 9.11.1), the cluster automatically selects supported TLS protocols TLSv1.3,TLSv1.2,TLSv1.1.
  • If you enable the FIPS-compliant mode (at 9.11.1 or), the cluster automatically selects only supported TLS protocols TLSv1.3,TLSv1.2
  • Use the -supported-protocols parameter to include or exclude TLS protocols independently from FIPS mode.
  • By default, FIPS mode is disabled, and ONTAP supports the TLSv1.3, TLSv1.2, and TLSv1.1 protocols.
  • Starting in 9.9.1, a reboot is no longer required  to apply the security configuration.
  • At 9.11.1 or later, TLSv1.3,TLSv1.2 can not be disabled, even once FIPs mode is disabled
