Stopping or starting a virtual network function or a VDU that is part of it

You can stop a virtual network function or a VDU that is part of it to free up the computational resources of the OpenStack cloud platform.

When you start a virtual network function or VDU, it begins consuming computational resources again. This restarts the processes running on the virtual network function or VDU.

To stop or start a virtual network function or a VDU that is part of it:

1. On the self-service portal, go to the Catalog menu section.

   The network service management page is displayed.

2. In the Network services pane, click the deployed network service to whose topology the virtual network function has been added.

   The topology is displayed.

3. Click the virtual network function.

   The settings area is displayed in the lower part of the page. You can expand the settings area to fill the entire page by clicking the expand icon . By default, the Flavours tab is selected, which displays flavours.

4. If you want to stop or start the virtual network function, in the upper part of the settings area, click the Management → Power → Stop VNF or Start VNF.
5. If you want to stop or start a VDU that is part of the virtual network function:
   1. Select the VDU management tab.

      A table of VDUs is displayed.

   2. Click Management → Power → Stop VDU or Start VDU next to the VDU that you want to stop or start.
6. In the confirmation window, click Apply.

The virtual network function or its VDU is stopped or started.
