Preparing the System
Before you enable FIPS mode, Dell Networking recommends making the following changes to your system.
1 Disable the Telnet server (only use secure shell [SSH] to access the system).
2 Disable the FTP server (only use secure copy [SCP] to transfer files to and from the system).
3 Attach a secure, standalone host to the console port for the FIPS configuration to use.
Enabling FIPS Mode
To enable or disable FIPS mode, use the console port.
Secure the host attached to the console port against unauthorized access. Any attempts to enable or disable
FIPS mode from a virtual terminal session are denied.
When you enable FIPS mode, the following actions are taken:
• If enabled, the SSH server is disabled.
• 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 amount of time. In general, this failure can occur if a user at a remote host is in the
process of establishing an SSH session to the local system, and has been prompted to accept a new
host key or to enter a password, but is not responding to the request. 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.
CONFIGURATION
fips mode enable
The 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) ?
