2.5 Ordering
Some NNMi console configuration forms include the Ordering attribute, which sets the priority for applying the configurations. For one configuration area, NNMi evaluates each item against the configurations from the smallest (lowest) ordering number to the next lowest ordering number, and so on, until NNMi finds a match. At that point, NNMi uses the information from the matching configuration and ceases to look for any more matches. (The communication configuration is an exception. NNMi continues to search for information at other levels to complete the communication settings.)
The Ordering attribute plays an important role in NNMi configuration. If you see unexpected discovery or status results, check the ordering of the configurations for that area.
Ordering numbers are also used in the following places, but with different meanings:
-
For ordering menus and menu items, in which case you specify an order for applicable menus that is appropriate within the local context.
-
For ordering topology maps on the Node Group Map Settings form, which sets the order of items in the Topology Maps workspace.
For specific information about how the Ordering attribute affects a given configuration area, see NNMi Help for that area.
- Tip
-
-
For each configuration area, apply low ordering numbers to the most restrictive configurations, and apply high ordering numbers to the least restrictive configurations.
-
For each configuration area, all ordering numbers must be unique. During initial configuration, use ordering numbers with a standard interval to provide flexibility for future modifications to the configuration. For example, give the first three configurations the ordering numbers 100, 200, and 300.
