Client 1+1 protection is created based on client 1+1 protection groups. To create client 1+1 protection, you need to create a client 1+1 protection group for each node.
Prerequisites
The working and the protection OTU boards must be installed.
The SCS, DCP or OLP boards must be installed.
Background Information
The client 1+1 protection can be implemented in the following two ways:
- The working and the protection OTUs are installed in the same shelf. The SCS can realize the client 1+1 protection.
- The working and the protection OTUs are not in the same shelf or even the same ONE. The OLP or DCP board can be used to realize the client 1+1 protection.
In the case of the client 1+1 protection, you need to create a protection group at both the source and sink NEs to achieve bidirectional protection.
Precaution
NOTICE: When creating the client 1+1 protection, adhere to the following principles:
- For the L4G and TBE board, the client 1+1 protection and the VLAN SNCP cannot be created at the same time.
- For the L4G and TBE board, the client-side port attributes of the corresponding channels of the working and protection boards must be the same. Otherwise, the services are not available.
- The client 1+1 protection and the LPT function cannot be applied at the same time.
Procedure
- Click the NE in the NE Explorer, and choose from the function tree.
- Click New in the Port Protection interface.
- In the Create Protection Group dialog box displayed, select Client 1+1 Protection from Protection Type.
- As for the client 1+1 protection that adopts the SCS, the control unit of the protection group does not need to be configured. Meanwhile, NE with Control Channel/Monitoring Channel should be set to NULL.
- As for the non-intra-shelf client 1+1 protection that uses the OLP or DCP board, the board with Control Channel/Monitoring Channel should be set to OLP board or DCP board.
NOTE: When you use an OLP to configure inter-shelf or inter-NE client 1+1 protection, in the Control Channel/Monitoring Channel, choose interface 1(RI1/TO1) of the OLP. Otherwise, the protection units cannot work normally. Similarly, for the DCP, choose only interface 1(RI11/TO11) or interface 3(RI21/TO21).
- Click OK. The Operation Result dialog box prompts that the operation is successful. Click Close. The created protection group is displayed in the interface.
- Start the NE Explorer of the opposite NE. Then, refer to Steps 1 through 5 to create the client 1+1 protection on the opposite NE, to create the reverse protection.
- Optional: Select one protection group and select at the bottom of the interface.
- Optional: Click Delete. Click OK on the Confirm dialog box displayed. The Operation Result dialog box prompts that the operation is successful. Click Close. The protection group can be deleted.
