The SNCP service features the dual fed and selective receiving function and is used to protect cross-subnet services. When configuring SDH services on a per-NE basis, you can perform this operation to convert a configured non-protection service to an SNCP service.
Background
NOTICE: Converting a non-protection cross-connection service to an SNCP service may interrupt services.
Procedure
- In the NE Explorer, select an NE and choose from the Function Tree.
- Click Query to query the SDH services from the NE.
- Select a non-unidirectional service, Click Display and choose Expand to Unidirectional from the drop-down menu.
NOTE: You can select multiple services to change them in batches.
- Right-click a desired non-protection service and choose Convert to SNCP from the shortcut menu.
- In the Prompt dialog box displayed, click OK.
- In the Create SNCP Service dialog box displayed, configure the protection service and click OK.
NOTE:
You need to perform the operation on the NEs that are set as the dual fed nodes and selective receiving nodes on the source or sink, or in the cross protection.
- Click Create. In the Create SDH/PDH Service dialog box displayed, configure a unidirectional service from the service source board to the line board of another direction.
NOTE:
You need to perform the operation on the NEs that are set as the dual fed nodes and selective receiving nodes on the source or sink, or in the cross protection.
- On the intermediate NE that protection services pass through, configure bidirectional pass-through services between line boards.
NOTE:
You need to perform this operation on all the intermediate NEs that protection services pass through.
