Default LAN Configuration Settings Set by the SMU
The SMU automatically configures some server management firmware settings. These are not
displayed on the screen above, but are listed below. Before these settings are set by the SMU, you
must click through each LAN configuration screen by clicking the Next button until you reach the
Save button on the final LAN configuration screen.
• Gratuitous ARPs may be enabled: This setting allows the BMC to generate gratuitous ARPs,
which provide a mechanism for IP devices to locate the hardware addresses of other devices
on the local network. If the system has a valid IP address and the LAN channel is enabled for
messaging (the access mode is not set to Disabled) or alerting, then gratuitous ARPs are
enabled.
• Authentication enables are enabled: These bits define what types of authentication are
enabled to authenticate messages sent to the BMC by users of different privilege levels. The
SMU enables authentication of type straight password, MD2, MD5, and none.
• User-level authentication is disabled: The SMU disables user-level authentication so that if a
user is attached with a privilege level of User, no authentication is done on messages sent to or
from the BMC. This improves the session performance.
