For details about how the order of list entries in a template is affected by configuration
groups, see “Using Configuration Groups” on page 223. The following sections describe
how the order of lists is affected by template position, device object data, the order on
the device itself, and the operations that affect the sequence of ordered list entries.
• Combining Template Data with Device Object Data on page 212
•
Operations That Change the Sequence of Ordered Lists on page 212
•
Rules for Reordering Lists on page 213
• Examples of Reordered Lists on page 213
• Identifying Ordered List Entries That Do Not Match the Template or Configuration
Group Order on page 216
Combining Template Data with Device Object Data
If a template and the device each have data for an ordered list, by default, NSM places
the template entries after the device entries. For example, suppose a device object has
two entries for an ordered list:
D1 D2
A template has two list entries for the same list:
T1 T2
When you apply the template to the device, NSM applies the default ordering, which is
to place the template entries after the device entries:
D1 D2 T1 T2
Now push the configuration to the device, and then connect to the Web UI of the device
and reorder the list entries, such that the list entries that came from the template are
reversed:
D1 D2 T2 T1
Now consider what happens when you reimport the configuration from the device. To
preserve the relationship between the template and the device object, the T1 and T2
entries must continue to refer to the template. Yet the order must be preserved to
correspond to the device. Because another device using the template might give the
entries a different order, NSM must keep the ordering information on a per-device basis.
Operations That Change the Sequence of Ordered Lists
By default, template entries appear at the end of each ordered list in template priority
order, followed by entries specified in the device object data. Through changes on the
device outside of NSM, or through user action, template-provided list entries can be
reordered and intermixed with list entries provided in the device object. The following
operations can affect the order of list entries in the device object:
•
Adding a template
•
Deleting a template from the device object
• Adding or inserting new list entries in the template
• Adding or inserting new list entries in the device
