    Configuring Services Interfaces

    This topic describes how service providers configure services physical interface cards (PICs) for advanced router cCPE services such as NAT.

    To provide advanced cCPE services like NAT, you must install and use services line cards in your MX Series routers to provide adaptive services interfaces, which allow you to coordinate multiple services on a single PIC by configuring a set of services and applications.

    To provide functionality such as the basic NAT service, you need to define blocks of service interface units or logical unit numbers on the PIC in your MX Series router. The block of logical unit numbers define the range of units reserved for Selfcare Portal use.

    When you create a NAT service, two logical interfaces are assigned to the NAT service:

    • One logical interface facing the customer site, to translate outgoing data
    • One logical interface facing externally, to translate incoming data

    Service providers can create, modify, and delete logical interfaces on services PICs through the Selfcare Portal.

    Note: Because the two logical unit numbers from the block are assigned when a NAT service is created, the blocks must contain an even number of units. In addition, the Upper Logical Unit value must be the higher than the Lower Logical Unit value. Only one block of units can be assigned per physical interface, so the Device name and Interface name combination must be unique.

    To configure the block of logical unit numbers reserved for Selfcare Portal:

    1. In the Selfcare Portal task pane, select Administration > Resource Management
    2. Select the Services Interfaces tab.

      The Services Interfaces page appears in the content pane, an example of which is shown in Figure 1.

    3. Select the Add (+) icon.

      A new row is added to the Services Interfaces group box.

    4. From the Device list, select the name of the router on which the interface resides.
    5. In the Interfaces field, specify the name of the services interface providing the service, for example sp-3/1/1.
    6. In the Lower Logical Unit and Upper Logical Units fields, specify the logical unit numbers for the interface.
    7. In the Description field, specify a description for the services interface.
    8. Select Update to save your changes.
