Issue Description

From U2000, we can search for RTN 950 using NE ECC Link Management (NE 1830) but I can’t access it.
This RTN is a far end of MW link.
DCC Management is enabled also Ethernet Port OAM Management is enabled.
we can '' Discover '' in U2000 but can not add in toplogy.

Alarm Information

''1''. No alarm
''2''. when discover NE from U2000 ,Find it but can not create . error message '' NE busy''.

Handling Process

''1''. Try to change access usernames ''szhw'', ''root'' ,''lct'' to access navigator and from U2000, but no response .
''2''. Checked in DCC Management, and check IF board DCC in both end of the link. The communication status should be OK.
''3''. Upload U2000 log.
''4''. From logs and intersite by using navigator, we find another RTN has same IP address by using
after change the IP , the RTN950 can monitor.(attchment results)

Root Cause

''1''.From direct connection to RTN in site , we can access to NE by using Navigator.
''2''. check the RTN ID, if duplicated ID in U2000.
''3''. change RTN ID from local connection.
''3''. Check the DCC managment in both end of the link, the result was OK.

For huge network , we must prepare ID and IP network plan for all NE in same managment system and be sure no IP repeated.
