Issue Description

1. Inside NMS ( Network Management System) iManager U2000 appears red icon with an arrow pointing right

Alarm Information

The NE_DATA_INCONSISTENCY alarm indicates that the data on the NE that reports alarms is inconsistent with the data on the U2000.

Possible Causes:

-Data inconsistency between NEs and the U2000 may be caused by the modification on NE configuration with command line tools.

-Assume that an NE is managed by multiple NMSs. After data is modified on one NMS, data on the NE is inconsistent with data on another NMS. As a result, the NMS report this alarm.

Handling Process

first one verify  Synchronous Status  if has Unsynchronized to check data consistency between an NE and the U2000 by comparing configuration data on NEs with that on the U2000. After the check, a report of the result is created. If the result shows the configuration data is inconsistent, you need to upload the configuration data from the NE to the U2000 or download the data from the U2000 to the NE for data synchronization.



Root Cause

When the U2000 detects data inconsistency between NEs and
the U2000, it reports the alarm. When data inconsistency occurs, it causes the
following results:

The synchronized data reported from NEs changes The U2000 regularly detects that the final synchronization serial numbers (SNs) are inconsistent. Manually querying the synchronization data triggers the detecting of the final synchronization SNs. The alarm is cleared when the data synchronization is performed. Data synchronization operations include uploading, synchronizing, and downloading NE data.


1.- Right-click an NE in the Main Topology and choose Upload from the shortcut menu.


2. Select one or more NEs from the Object Tree and click , For NEs whose Logged in is Yes. The NE Configuration Data Management window is displayed, and a Confirm dialog box is displayed.


3.- waiting progress

4. Click Close in the Operation Result dialog box.


 5.-you can see Synchronous Status:  Synchronized


 6.- Icon cleared



 7.- Alarm has been cleared
