65MAXDATA PLATINUM 90002R Server System
Default LAN Conguration Settings Set by the SMU
The SMU automatically congures some server management rmware 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 conguration screen by clicking the Next button until you reach the Save
button on the nal LAN conguration 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 dene 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.
Access Mode
This drop-down box congures the access mode for the LAN channel. The available options are:
• Always Available: The channel is dedicated to communication with the BMC and is available
during all system states (powered-down, powered-up, pre-boot, sleep, run-time, etc.).
• Disabled: The channel is not allowed to communicate with the BMC.
Privilege Level Limit
This drop-down box determines the maximum privilege level at which communication on the channel
can take place. It is a global privilege level that takes precedence over user privilege levels. For example,
if a channel privilege level is set to the user level then only user-level commands can be executed,
regardless of the user privilege level.
The meanings of the different privilege levels are described below:
• Callback: Only commands needed to initiate a callback session are allowed. Although ISM
software does not support callback as a connection mechanism, it is still a valid privilege level
because it denes a set of BMC commands that can be executed by a user.
• User: Only “benign” commands are allowed. These are primarily commands that read data
structures and retrieve status. Commands that can be used to alter BMC conguration, write
data to the BMC or other management controllers, or perform system actions such as resets,
power on/off, and watchdog activation are disallowed.
• Operator: All BMC commands are allowed, except for conguration commands that can change
the behavior of the out-of-band interfaces. For example, Operator privilege does not allow the
capability to disable individual channels, or to change user access privileges.
• Administrator: All BMC commands are allowed, including conguration commands. An
adminstrator can execute conguration commands that would disable the channel that the
Administrator is communicating over.
Enable DHCP
The Enable Dynamic Host Conguration Protocol (DHCP) check box enables / disables the dynamic
host conguration protocol to allow the server to automatically assign the Host IP address, Default
Gateway IP address and Subnet Mask. DHCP is enabled when the box is checked.
When this option is enabled, the Host IP Address, Subnet Mask, and Default Gateway IP Address
edit boxes are disabled. The system must be reset before this setting takes effect.
