Hi there!
This time, I will share with you a case about Loopback status will be automatically released after set the VC12 loopback.
Issue Description：
Loopback status of NGSDH NE SDH path will be automatically released after setting the VC12 loopback:
Handling Process
Open oss / server / etc / oss_cfg / e2e / nml_sdh / nmlsdh.cfg
Modify the value of this item:
LoopClearInterval = 30 -> into 300000000 this unit is seconds
Restart Nml_sdh, restart the client.
Root Cause
1、The timing release is achieved by E2E itself. The front desk has an entrance, you can set the loop to automatically lift the time. Each loopback records the loopback release time.
2、The mechanism is that the background polls for 30 seconds by default. If the time for releasing the loopback is less than the current system time, the loopback reported by the NE will not be released when the loopback is released. The E2E default setting is 0,
3、The default background polling time of 30 seconds once, to determine the loopback time has come, so issued a loopback release command
Solution
The issue will resolve at patch R17C50CP2102
That's all, welcome everyone to leave a message and exchange in the comment area!
