The order of the filters in a set does not matter, and you cannot reorder the filters after you
have created them. What matters in this structure is properly grouping the filters with
respect to the selected
OR and AND operator options.
Š
Add filter set: Adds the next filter as a filter set with either AND or OR placed between
the filter sets, as dictated by your selection in the Combine filters using field.
To create filter sets, first click Add filter set , then click Add filter as many times as
necessary to add filters into that set.
You cannot insert filter sets between existing filter sets.
Š
Delete: Deletes any filters that are selected (see Check box below in Step 12 ).
11 To determine the filter and filter set logic, select AND or OR from the Combine filters using
drop-down list.
The logical operator you select here determines which operator is used within the filter sets.
The operator for this field applies to multiple sets.
To provide multiple sets for the rule, indicate whether the sets should all be required (select
AND ) or are all optional (keep OR ). If OR, then the values in only one of the sets need to match
the device for the rule to apply. If AND, then all values in the entire rule must match the device
for the rule to apply.
If you only have one filter set (which could contain several filters), AND is the default logical
operator within the set, because OR defaults in the
Combine filters using field, which you can
change.
Filter sets will be combined using is a display-only field. When providing multiple sets for the
rule, this field displays the opposite logical operator from the one you select for the Combine
filters using field.
To require all filters within a filter set, but only one of the filter sets, select OR in the Combine
filters using field. To require all filter sets, but only one of the filters within each set, select
AND in the Combine filters using field.
12 To configure rule filters, fill in the fields:
Š Check box: Selects filters for deletion.
Š
Drop-down list: If blank, this field means to do as worded in the filter. If you select NOT ,
it means to do the opposite of what the filter says.
For example, if you select
NOT and the RAM size is configured to be “less than 512 MB,”
then the device must have at least 512 MB of RAM for the bundle to be applied. In other
words, the filter reads “not less than 512 MB of Ram.” Conversely, if you configured it as
“more than 512 MB,” then left the field blank, any computer containing exactly 512 MB
of RAM is excluded, which you might not intend. So, be sure that you think the logic
through for your filter configurations with respect to whether you use NOT.
Š Device component: A drop-down list provides the various items available for matching
on the device in order to determine whether the work rule applies for the bundle. The
options are:
BIOS Asset Tag
BIOS Serial Number
BIOS Version
CPU Chipset
Hard Disk Controller
Hard Drive Size (in MB)
