  2. In the left-side navigation pane, click VSwitches.
  3. In the top navigation bar, select a region.
  4. On the VSwitches page, click Manage in the Actions column corresponding to the target VSwitch.
  5. On the VSwitch Details page that appears, find the VSwitch Basic Information section. Click Change next to Network ACL.
  6. In the Bind Network ACL dialog box that appears, select the target network ACL. Click OK.
