In country X, We received the problem: We are facing serious problem in Alarm Monitoring. After we switched to server 172.20.68.7 we are facing Intermittent Association (not stable) and false critical alarms are generating (see attachments). Version: U2000 V100R002C01SPC003.
NE_NOT_LIGIN alarm is generated when an NE is not logged in. possible causes is:
1.The communication between the NE and the U2000 is interrupted.
2.The user logs out of the NE or fails to log in.
1.Clear the alarm buffer to remove remaining NE_NOT_LOGIN alarms.
2.Troubleshoot the problem in the SDH NE management process.
The issue has been solved in patch U2000V1R2C01CP0304 The link of is:
1.The U2000 SDH NE management process ran improperly. The U2000 HA system switched over.
2.During the switchover, the DCN was disconnected. Therefore, the HA system remains in the active/active state.
3.In this case, two servers in the HA system were active servers. When two same users tried logging in to an NE, a large number of NE_NOT_LOGIN alarms were generated on the U2000.
4.Because the U2000 HA system switchover was interrupted, some alarm messages were still stored in the buffer. After the HA system was recovered, a large number of NE_NOT_LOGIN alarms continue to be reported on the U2000.
