Alarm Information

error: 0x971c NSERR_CFG_BAD_AU4ID  

Handling Process

R&D resume the database of the NE in lab, create the MSP(Multiplex Section Protection), report error. 

1,Using T2000 to upload the NE and delete the NE database, 

2, Download configuration to NE, then can create MSP (Multiplex Section Protection)successfully. 

So the reason of this problem is NE database abnormal, need to delete the NE database and download configuration from T2000 again.

Root Cause

1, the MSP(Multiplex Section Protection) configuration  wrong;
2, the problem of GSCC
3, the problem of Cross connection board
4, the problem of line board

Suggestions

In some case, some abnormal problem may caused by NE database abnormal, delete the NE database and download from T2000 again, the NE database can be 
normal.
