FIPS mode configuration B Power-on self tests A power-on self-test (POST) is invoked by powering on the switch in FIPS mode and does not require any operator intervention. If any KATs fail, the switch goes into a FIPS Error state, which reboots the system to start the test again. If the switch continues to fail the FIPS POST, you will need to return your switch to your switch service provider for repair. Refer to the Fabric OS Troubleshooting and Diagnostics Guide for information about preparing a case for your service provider. Conditional tests These tests are for the random number generators and are executed to verify the randomness of the random number generator. The conditional tests are executed each time prior to using the random number provided by the random number generator. The results of the POST and conditional tests are recorded in the system log or are output to the local console. This action includes logging both passing and failing results. Refer to the Fabric OS Troubleshooting and Diagnostics Guide for instructions on how to recover if your system cannot get out of the conditional test mode. FIPS mode configuration By default, the switch comes up in non-FIPS mode. You can run the fipsCfg --enable fips command to enable FIPS mode, but you must configure the switch first. Self-test mode must be enabled before FIPS mode can be enabled. A set of prerequisites (as shown in Table 87) must be satisfied for the system to enter FIPS mode. To be FIPS-compliant, the switch must be rebooted. For directors, either reboot both CPs, or power the chassis down and then up again. KATs are run on the reboot. If the KATs are successful, the switch enters FIPS mode. If the KATs fail, then the switch reboots until the KATs succeed. If the switch cannot enter FIPS mode and continues to reboot, you must return the switch to your switch service provider. For information about how to prepare a service provider case, refer to the Fabric OS Troubleshooting and Diagnostics Guide. When the switch successfully reboots in FIPS mode, only FIPS-compliant algorithms are run. NOTE RPC is not supported in FIPS mode. Table 87 lists Fabric OS features and their behaviors in FIPS and non-FIPS mode.
