Hello everyone,

Today I want to share with you how to deal with synchronization between U2000 and MPLS Routers is abnormal.

Several issuesRegarding synchronization between U2000 and the whole MPLS network appear incustomer network.

For example, when trying to access to NE IP Address Management in NE explorer, the operation is failed:


Additional issues appear constantly such as alarms failing to synchronize with the topology.

The following is the procedure to handle this issue: 

1. Test SNMP connectivity between U2000 and the devices, if Test is failed, go to the next step, otherwise go to step 3.


Select the device and click test

2. Validate the SNMP configurations and IP connectivity and fix accordingly. End.

3. Restart the RouterMgrDm_1 process: Login to U2000 System Monitor, select the RouterMgrDM_1 process and right-click and then click stop, wait for around 2 minutes and then start the process again.

4. Restart the U2000 client and validate whether the issue persists. Normally this solves the issue, if the issue is not solved, please do as follows:

a) Reproduce the issue, and make a video or make full screenshot to record the

operation time (open NE Explorer, sync device and sync Alarm)

b) Collect below logs around operation time:

Alarm issue


Send the information to  R&D for analysis. 

That is all I want to share with you. Thank you!
