Problem Description

After OSN3500 has enabled the smart feature for quad synchronization, the SDH smart path management prompts "no link connection for network element" for new smart path.

Process

1. Check that the ECC communication 9-byte mode is on and normal.

2、Check the intelligent characteristic management is normal.

3. Check that the LMP protocol management status and operation status are normal.

4. Check that the OSPF protocol management status is normal.

5、Check the SDH intelligent topology management, network elements all belong to the same intelligent domain (note that if not in the same intelligent domain, you need to manually delete a smart domain and then synchronize).

6、Verify that the TE link management interface is normal and there is a TE link.

7. Verify that the upload operation must be done after opening the intelligent characteristics, otherwise some basic attributes of the intelligence are not synchronized to the network management, resulting in incomplete links in the intelligent link management of the network management, and intelligent services cannot be created.

8, on the newly opened intelligent network elements to do the upload operation, and then the four-step synchronization, the problem is solved.

Root cause

After the smart feature is turned on, you must do the upload operation, otherwise some basic attributes of the smart are not synchronized to the network management, resulting in incomplete links in the smart link management of the network management, and you cannot create smart services.

Solution

Do the upload operation for the newly opened smart network elements, and then do the four-step synchronization.

Suggestions and summaries

It is recommended to do the upload operation first, and then do the four-step synchronization for the newly opened smart network elements.

In order to ensure that the network management and equipment synchronization, end-to-end formation of business path, to facilitate routine maintenance and management, the need to use the "four-step approach", including.

1, synchronization network element cross. Network management menu for the configuration-SDH intelligent-intelligent topology management

2, synchronization TE Link, network management menu for the configuration-SDH intelligent-TE link management.

3、Synchronize Smart Path and refresh the actual route of Smart Path. The network management menu is Configuration-SDH Intelligence-Intelligent Circuit Management and Maintenance-Refresh Actual Route.

4、Path search. The network management menu is Path-SDH Path Search.
