Change Request Workflow

Change control management provides authorization and tracking for change requests related to tunnels.

The following procedure explains the workflow of a change request. Based on your user role, you can perform one or more of the following steps:

  1. Create and submit a change request.
    Note:

    You can create a change request only if you have either the Create or Auto-approve permission assigned to your user role.

    To create and submit a change request:
    1. Navigate to the Tunnel tab in the network information table (Network > Topology).
    2. Perform the task (add, modify, or delete tunnels) appropriate for the desired request.
      After you complete the task, a change request is automatically created for the task and is submitted to the change control management system.

      The request appears on the Change Control Management page (Network > Change Control Management) with Status as Submitted.

    If you have the Auto-approve permission assigned to your user role, the requests are approved and deployed automatically upon submission. If you don't have this permission, you or a user having the Approve permission must approve the request. See Step 2.
  2. Approve or reject a change request.
    Note:

    You can approve or reject the change request only if you have the Approve permission assigned to your user role.
    To approve or reject the change request:
    1. On the Change Control Management page, select the request that you want to approve and click Approve. Alternatively, click Reject to reject the request.
      The Approve Change Request request-id page or Reject Change Request request-id page appears, based on what you selected in Step 1.
    2. (Optional) Add a comment and click OK.
      A confirmation message appears on top of the page, and the status of the request changes accordingly.
  3. Deploy the approved change request on the network for the request to take effect.
    Note:

    You can deploy the change request only if you have the Deploy permission assigned to your user role.
    To deploy the change request:
    1. Select the request that you want to deploy, and click Deploy.
      The Deploy Change Request request-id page appears.
      Note:

      This step is not applicable when change requests are auto-approved. Auto-approved change requests are approved and deployed automatically upon submission.

    2. You can choose to start deployment immediately (Activate Now) or schedule the deployment for a later date and time (Activate Later).
    3. (Optional) Specify a comment for the request.
    4. Click Deploy.
    After a change request is scheduled, the status of the request changes to Scheduled.

    When you deploy this request at the scheduled time, the status changes to Activated. The Path Computation Element (PCE) provisions the tunnel and the tunnel appears in the network information table (Tunnel tab) in the Topology page.

  4. (Recommended) Archive (close) the approved, activated, or rejected change requests when they are no longer needed.
    Note:

    You can archive a request only if you have submitted it. You cannot archive requests that are submitted by other users.
    To archive a request:
    1. Select a request with the Status Rejected, Approved, or Activated, and click More > Archive.
      The Archive Change Request request-id page appears.
    2. (Optional) Specify a comment in the Approver Comments field.
    3. Click Archive.
    A confirmation message appears on top of the page, indicating that the change request is closed. You can view this request (Status: Closed) in the Archived tab on this page.
