Issue Description

Cusotmer buy our eSight software. After finish the installation, he wants to add one AR router into eSight. But it is failed and get below error: The NE already exist.

Alarm Information

The NE already exist.

Handling Process

1. Search the IP of AR router in eSight. And did not find that IP.
2. We think the the error is because of MAC conflict. Collect the logs and the diagnostic information of AR router.
AR has two MACs: ac4e-9144-4a5c and ac4e-9144-4a5d

In NE_INFO table, there is already one AR157 on eSight.
NE=34603009     XXXX XXXX  AR157W     Huawei  XXXX      AC-4E-91-44-4A-5C    AR157WV200R003C01SPC900

We found the reason. Because of MAC conflict, cannot add device into eSight.

3. Provide two solutions to customer:
a. Change the MAC address of added AR router
b. Use the IP of eth0/0/8 which MAC is XXXX-XXXX-XXXX to add AR201 to eSight.

4. Customer found the conflicted device is not used and delete it from eSight. Add new AR router to eSight successfully.
