• All open SSH and Telnet sessions, as well as all SCP and FTP file transfers, are closed.• Any existing host keys (both RSA and RSA1) are deleted from system memory and NVRAM storage.• FIPS mode is enabled.– If you enable the SSH server when you enter the fips mode enable command, it is re-enabled for version 2 only.– If you re-enable the SSH server, a new RSA host key-pair is generated automatically. You can also manually create this key-pair using the crypto key generate command.NOTE: Under certain unusual circumstances, it is possible for the fips enable command to indicate a failure.• This failure occurs if any of the self-tests fail when you enable FIPS mode.• This failure occurs if there were existing SSH/Telnet sessions that could not be closed successfully in a reasonable amountof time. In general, this failure can occur if a user at a remote host is in the process of establishing an SSH session to thelocal system, and has been prompted to accept a new host key or to enter a password, but is not responding to therequest. Assuming this failure is a transient condition, attempting to enable FIPS mode again should be successful.To enable FIPS mode, use the following command.• Enable FIPS mode from a console port.CONFIGURATIONfips mode enableThe following warning message displays:WARNING: Enabling FIPS mode will close all SSH/Telnet connections, restart those servers,and destroy all configured host keys. Proceed (y/n) ?Generating Host-KeysThe following describes hot-key generation.When you enable or disable FIPS mode, the system deletes the current public/private host-key pair, terminates any SSH sessionsthat are in progress (deleting all the per-session encryption key information), actually enables/tests FIPS mode, generates new host-keys, and re-enables the SSH server (assuming it was enabled before enabling FIPS).For more information, refer to the SSH Server and SCP Commands section in the Security chapter of the Dell Networking OSCommand Line Reference Guide.Monitoring FIPS Mode StatusTo view the status of the current FIPS mode (enabled/disabled), use the following commands.• Use either command to view the status of the current FIPS mode.show fips statusshow systemExamples of the show fips status and show system CommandsThe following example shows the show fips status command.Dell#show fips statusFIPS Mode : Enabledfor the system using the show system command.The following example shows the show system command.Dell#show systemStack MAC : 00:01:e8:8a:ff:0cFIPS Cryptography 323
