Access Mode
This drop-down box configures 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 defines 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 configuration,
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 configuration 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 configuration commands. An
adminstrator can execute configuration commands that would disable the channel that the
Administrator is communicating over.
Enable DHCP
The Enable Dynamic Host Configuration Protocol (DHCP) check box enables / disables the
dynamic host configuration 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.
Host IP Address
This edit box is for the logical or Internet address of the host. The IP address is required when
DHCP is disabled. The IP address is entered as a dotted notation, such as 192.168.0.2.
Subnet Mask
The edit box is for the host’s subnet mask. The server uses this to decide if alert destinations
are in the local subnet or in another subnet relative to the client console. The Subnet Mask is
required when DHCP is disabled. The Subnet Mask is entered as a dotted notation, such as
255.255.0.0.
Default Gateway IP Address
This edit box is for the IP address of the router used when the BMC sends a message or an alert
to a system on a different subnet than the BMC is on. It is required when DHCP is disabled.
The IP address is entered as a dotted notation, such as 192.168.0.2.
