Problem:
-------------------------------------------------------
after upgrading HPE IMC to version 7.3 E0706P06 there are many many log messages like:
Interface Switch loopbackup interface-5073 of device, address 127.0.0.1 is duplicate

cause:
A new Duplicate IP trap has been added in IMC 7.3 E0706P06, and does not ignore the loopback address.

Workround:
1. Stop imcnetresdm process in IDMA

2. Back up $IMC/server/conf/qvdm.conf to the desktop.

3. Edit the original file, adding the line at the end of the file:
DupIpConflictAlarm=false
add another blank line and save the file.

4. Start imcnetresdm process in IDMA
