Set Border Rules on a Link

By default, consumer-provider relationships between CIs are internal, meaning that they are contained within a service model. Use the service border rules functionality to define which relationships are actually external to your service trees.

  1. In the Service Model dashboard, click an existing service model.
  2. Hover your mouse over a CI in the map and select Border rules on link from the context menu .

  3. Select a link from the displayed list.
  4. Click . The following settings for the border rule are displayed:

    Field Description
    Name*

    Enter a name for the border rule. (Mandatory)

    References

    Describes one or more conditions on the References attribute of the selected consumer-provider link.

    You can enter comma-separated values.

    Consumer

    In this section, you define specify a CI type and attribute conditions for End 1 of the consumer-provider link.

    Attributes that have already been defined on the model automatically populate the corresponding fields here.

    Note Only attributes of type string or enum appear in the list.

    Provider In this section, you specify a CI type for End 2 of the consumer-provider link.

    Note Carefully verify that the attributes you set actually contain values that you specify for border rules. Otherwise, you will not be able to access the border rule in the UCMDB Browser. You will be able to access the border rules in UCMDB in Data Flow Management > Adapter Management > <<No Package>> resource > Configuration Files.

  5. When you are finished, click .

When a link is affected by a border rule during a discovery run, the Data Flow Probe updates the following attributes on the consumer-provider dependency link:

  • Is External is updated from False to True.
  • Service Border Rules is updated to include the names of the border rules that affect the link.

Note  

  • When you add a border rule, the link does not immediately change to External (indicated with a dotted line for the link). Adding a border rule updates a configuration file on the Data Flow Probe. After the discovery process runs, the relationship in the topology map will be marked as External, providing that the relationship matched the conditions on at least one service border rule.
  • When a virtual link is marked as External, and that link contains multiple links, if at least one contained link is external, this link will show up as External.
