1. How much is the CPU utilization and memory utilization as the device is normal?
A. it should be below 30％. Otherwise the device may be either abnormal or attacked. At this time, we can contact the Huawei Engineers to check the detailed reasons.
We should ensure the spare memory is more than 20M. Otherwise, the system will release some memory via the protecting mechanism to ensure the normal running the devices. These will affect the service. Check the spare memory via display memery limit.
2. For master/slave MPU switchover, normally, how long can we do master/slave MPU switchover for once? What are the key points?
A. normally, master/slave MPU switchover is unneeded, because NE40 is telecom-level device, it can satisfy the requirements of constant running. master/slave MPU switchover is used as solving problems.
If do master/slave MPU switchover, please perform data synchronous operation before that. In addition, recommend to save the data, to prevent the accidents. master/slave MPU switchover can be done as the occupying rate of CPU is not high. Otherwise, the service will be affected.
