Viewing Prestaging Rules

Prestaging rules contain criteria for classifying the MPLS role of each device and recommending which physical interfaces should be UNI interfaces. For each recommended UNI interface, the system recommends its primary loopback address.

These prestaging rules are predefined and cannot be configured. They are neither selectable nor configurable. However, you can modify the results of the rules before committing the recommended assignments to the database.

The following topics show how to view prestaging rules in either a graphical or a tabular view. You can view a summary of all prestaging rules, see a summary “quick view,” or view details of a specific prestaging rule.

Viewing Prestaging Rules as Graphics

To view the prestaging rules as graphics, follow these steps:

1. In the Ethernet Activator task ribbon, select the Prestage Devices workspace.
2. In the task ribbon, select the Manage Device Roles task.
3. In the task ribbon, select Rules.

   The Prestaging Rules screen appears.

4. In the Prestaging Rules screen header, select the thumbnail view icon.

   Thumbnails representing each of the prestaging rules appear. Figure 1 shows an example.

   Each thumbnail contains a decoration in the top left corner that identifies the type of check the rule performs and a unique name that identifies the specific rule. Table 1 explains each prestaging rule.

   Table 1: Prestaging Rules

   Name	Rule Type	Explanation
   Comment match		Checks whether the Comment field in the device configuration explicitly identifies the device as a PE device. The Comment field must contain “PE” if the device is to be assigned the PE MPLS role.
   Loopback check		Checks whether the loopback IP address is set in the device configuration. A loopback address must be set if the device is to be a assigned the PE MPLS role.
   BGP type		Checks whether EBGP is enabled for the device. Specifically, the rule checks whether the device configuration has configuration/protocols/bgp/group/type set to “external.” EBGP must not be enabled if the device is to be assigned the PE MPLS role. Devices with EBGP set are instead assigned the P role.
   Filter for Ethernet ports		Checks for Gigabit Ethernet (ge) or 10 Gigabit Ethernet (xe) interfaces.
   Filter for non IP ports		Excludes interfaces with IP addresses from UNI assignment.
   Vlan pool assignment		Depending on configured encapsulation, correct VLAN pool ranges are assigned to the UNIs: vlan-ccc—512 through 4094 flexible-ethernet-services—1 through 4094 flexible-vlan-services—1 through 4094 extended-vlan-ccc—1 through 4094

5. To view summary information about a specific prestaging rule, click the rule icon. The following summary information appears in the quick look panel to the right:
   • The name of the rule
   • The rule type; that is, whether it is an NPE rule, a UNI rule, or a VLAN allocation rule
6. To view additional details about a rule, double-click the rule thumbnail. The additional information includes a sample configuration that satisfies the rule:
   

Viewing Prestaging Rules in a Table

To view prestaging rules in a tabular format, follow these steps:

1. In the Ethernet Activator task ribbon, select the Prestage Devices workspace.
2. In the task ribbon, select the Manage Device Roles task.
3. In the task ribbon, select Rules.

   The Prestaging Rules screen appears.

4. In the Prestaging Rules screen header, select the table view icon.

   A table appears listing all the prestaging rules along with a brief description of each rule. See Table 1 for details.

5. To view summary information about a specific rule, select the rule in the table. The following summary information appears in the quick-look pane to the right:
   • The name of the rule
   • The rule type; that is, whether it is an NPE rule, a UNI rule, or a VLAN rule
6. To view details about the rule, including a sample configuration, double-click the table row. An example output follows:
