Pausing or unpausing a virtual network function or a VDU that is part of it

You can pause a virtual network function or a VDU that is part of it to pause processes running on it. However, the virtual network function or VDU continues to consume the computational resources of the OpenStack cloud platform. When you unpause a virtual network function or VDU, processes running on it are resumed.

   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 pause or unpause a virtual network function, in the upper part of the settings area, click Management → Pause VNF → Power or Unpause VNF.
5. If you want to pause or unpause a VDU that is part of the virtual network function:
