Š
Name servers: Controls which DNS servers a device uses. You can specify multiple DNS
name servers.
Š Device name: Configured device names can include a prefix, the BIOS asset tag, the BIOS
serial number, or none of these.
Š
IP configuration: For the IP configuration, you can specify to use DHCP or a specific IP
address. If you select to use IP addresses, you can provide a list using a range or by specifying
specific IP addresses. As devices are registered, they assume one of the available addresses. For
IP addresses, you can also specify a subnet mask and a default gateway.
For the procedures in configuring defaults for non-registered devices, see Section 29.4.3,
“Configuring Non-registered Device Settings,” on page 383 .
28.3.5 Preboot Work Assignment Rules
You can set up hardware-based rules for your Preboot bundles. Work assignment rules are used to
apply bundles to devices with specific hardware, or to match a broad set of hardware requirements.
For example, you can create a rule that applies a bundle to any device with a specific MAC address
or BIOS serial number. Rules like this can only match to a single device. On the other hand, you can
create a rule that applies to any device with at least 512 MB of RAM and 150 GB of hard drive
space.
A work rule is comprised of filters that are used to determine whether a device complies with the
rule. The rules use logic to determine whether a device meets the requirements for applying the
Preboot bundle. The AND and OR logical operators are used for creating complex filters for the
rule.
When a device is seeking work to be done, it scans the rules until it finds a rule where all of the
rule’s filters match the device, then executes the bundle assigned to the rule.
