LAN Channel Configuration Sub-task
The LAN channel configuration sub-task allows you to modify settings related to the LAN
channel. The initial screen for configuring the LAN channel is shown in the figure below. The
configuration settings are described below the figure.
Figure 26. LAN Channel Configuration
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,
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 provides 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.
