Hi, everyone!
Today I'm going to introduce you how to disable the automatic loopback release function on the U2000.
Problem Description
The loopback function is often used during fault diagnosis. The U2000 automatically releases the loopback, which affects fault locating. Therefore, you need to disable automatic loopback release on the U2000.
Handling Process
On the U2000, choose Configuration > NE Batch Configuration> Automatic Disabling of NE Function.
In the Automatic Disabling of NE Function box, search for the target NE and modify the parameters that forbid automatic release of loopbacks, as shown in the following figure.
Root Cause
The automatic loopback release function of the NE can be configured on the NMS. For details, see the handling process.
Solution
On the NMS, we can disable automatic loopback release.
To facilitate fault locating, you can disable automatic release of loopback on the NMS. However, it is not recommended that you disable automatic release of loopback unless otherwise required. This prevents line interruption caused by forgetting to release loopback.
That's all.
