Update IP Domain Membership Dynamically

In addition to selecting individual models for CA Performance Center IP Domain models, you can populate IP Domains with dynamic members. Adding dynamic members to the models that represent CA Performance Center IP domains lets you precisely populate IP domains with devices that belong to them.

Dynamic membership is based on rules and on search criteria that you specify. Dynamic members of a CA Performance Center IP Domain only remain in the CA Performance Center IP Domain as long as they meet the specified search criteria. Changes are automatically synchronized with CA Performance Center.

Follow these steps:

1. In the Explorer tab of the Navigation panel, navigate to the Global Collections node, and locate the CA Performance Center IP Domains.
2. Right-click a CA Performance Center IP Domain, and select Edit Global Collection.

   IP Domains are designated with a special icon:

   The Edit Global Collection dialog opens.

3. Click 'Search Options'.
4. Complete any of the following fields to create a single search expression:

   Attribute

   Specifies the attribute of a device to filter. From the drop-down list of commonly used attributes, select the attribute that you want to use. The predefined list might not include the attribute that you want. In this case, click Attribute to specify the model type (device, port, or other) and its associated attribute that you want to find.

   Note: If you choose an alphabetic attribute value, you can either clear (ignore) or select (include) the Ignore Case check box.

   Comparison Type

   Specifies the type of comparison to be made against the value that is specified in the Attribute field. Only the comparison types appropriate to the attribute data type are available.

   Ignore Case

   Determines whether the comparison is case-sensitive. If you do not select this check box, the comparison is case-sensitive. This selection is only enabled when it is appropriate for the data type of the attribute you selected.

   Attribute Value

   Enter the desired attribute value to search.

   Devices Only

   Specifies that the search results list includes only devices.

5. (Optional) To use a wildcard character or regular expression in the Attribute Value field, select a valid attribute in the Attribute field. Select 'Matches Pattern' in the Comparison Type field. Then select one of the following options:

   Specify Wildcard Now

   Lets you search for a value using a wildcard. For more information about the available wildcards, see the Modeling and Managing Your IT Infrastructure Administrator Guide.

   Specify RegExp Now

   Lets you create a search using Perl Compatible Regular Expression (PCRE) matching on attributes of the type 'text string'. Text string searches are available only for Matches Pattern comparison types. PCRE matching helps you to find and group models using specific pattern searches that are more advanced than existing searches or wildcard searches.

6. (Optional) Click the Show Advanced button to create a search that is based on a compound clause. For example you can choose to populate the CA Performance Center IP Domain based on existing Global Collections, or Secure Domain Connector information. For more information, see the Modeling and Managing Your IT Infrastructure Administrator Guide.
7. (Optional) Select the Real-Time Update check box.

   This option disables the update interval. It also adds or removes models from the CA Performance Center IP Domain when they meet or no longer meet the search criteria.

8. (Optional) Supply a value in the 'Run search to update Global Collection membership every <> hours' field.

   This value determines how often OneClick conducts a search to update the dynamic membership of the CA Performance Center IP Domain.

9. Click OK.

   The Search Options dialog closes and the Global Collection dialog opens.

10. Click Landscapes to identify the landscapes to include when searching models to populate the CA Performance Center IP Domain.
11. Click OK.

    The CA Performance Center IP Domain model now has a dynamic membership. Any adjustments that are automatically applied to the membership of this CA Performance Center IP Domain are synchronized to CA Performance Center.
