LAN Channel Configuration Sub-task
The LAN channel configuration sub-task allows settings related to the LAN channel to be
modified. The initial screen for configuring the LAN channel is shown in the figure below. The
configuration settings are described below the figure.
After completing this screen, click Next to move to the next screen to continue this sub-task.
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, the
user must click through each LAN configuration screen by clicking the Next button until the
Save button on the final LAN configuration screen is reached.
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 server 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.
