Issue Description

The physical ATM interface did not exist.

Alarm Information

N/A

Handling Process

1. use command : set workmode slot 0 vdsl atm
2. restart the device.
3. use command: display interface brief. The ATM interface displayed.

Root Cause

1. The ATM interface is built-in interface instead of a card.
2. The physical interface should display when use command "display interface brief". But it didn't display.
3. The light of ATM interface is flashing which means the hardware is OK.
4. when I checked all the physical interfaces with command "display interface brief" and found out there is an ethernet interface which should not exist.

5. Maybe the work-mode of hardware is not right.

Suggestions

Please check which kind of VDSL interface used most in the real network.
It is really hard to find this issue for the new costomer.
