Modify a Service Instance

Prerequisite

A superuser or network administrator can modify a service instance and provision the modified service in the network. When you provision a modified service instance, Paragon Automation generates a modify service order to provision the updated service. You can modify a service instance by uploading a preconfigured JSON file containing the changes. Alternatively, you can use the fields in the Paragon Automation GUI to modify the service-related parameters.

Note:

You cannot edit the Customer and Instance Name fields while modifying a service instance.

To modify a service instance:

  1. Click Orchestration > Instances.
    The Service Instances page appears.
  2. Select the service instance you want to edit and click the edit (pencil) icon.
    The Modify Service-Instance-Type page appears.
  3. In the General section, click Browse to upload a preconfigured JSON file that contains the modifications to the service instance.
    Alternatively, follow these steps to modify a service instance by using the GUI fields:

    • For L3VPN and EVPN, follow steps 4 and 5.

    • For L2 Circuit, follow steps 4 and 6.

  4. In the General section, modify the values in the fields, if applicable.

        4. Expand Placement and modify the placement parameters by referring to Table 1 for L3VPN services or by referring to Table 2 for EVPN services.

      Note:

      The Placement section is not available if:
