82 Configuration Software and Utilities
83MAXDATA PLATINUM 90004R Server System
This checkbox is checked by default unless the MAC address edit box appears to have a valid MAC
address. A MAC address of 00-00-00-00-00-00 is considered invalid, so the checkbox would get checked
when the SMU displays the view in that case. If the checkbox is unchecked, the default gateway
MAC address edit box becomes active (it is grayed out when this checkbox is checked). If it is still
checked when the OK button is clicked, the rmware immediately attempts to resolve the gateway
MAC address. If it cannot be resolved, a message is displayed to you stating that the address cannot
be resolved and that the MAC address should be entered.
Default LAN Conguration Settings Set by the SMU
The SMU also sets some server management rmware settings that are not exposed to you. The list
of these settings are given below: Note that for these settings to be set by the SMU, you must click
the Save button on the last LAN conguration view.
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 dene 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. (Refer to the IPMI specication for more information on these authentication
types.)
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 speeds up the performance
of the session.
LAN Alert Conguration
The LAN Alert Conguration view (see Figure 38) shows all currently congured destination IP
addresses for LAN alerts and their associated settings. If no IP addresses are currently congured
as alert destinations, the Edit and Delete buttons are grayed out.
