Hi friend!
Mobile network elements require more than the operator's authority, please confirm your authority.
Fabrication process(Product Version: V200R018C50)

Follow-up Procedure
If the clock function has been configured for NE 1, right-click in a blank area of the clock view and choose Synchronize with Physical View from the shortcut menu. NE 1 is then automatically moved to subnet B.
If subnet A, subnet B, and NE 1 also exist in a custom view, repeat the preceding operations in the custom view so that NE 1 can be monitored in the custom view.
Thank you!
