The customer's third-party NMS collects the CPU usage data of the MPUs on two NE40E-X8s. The data collected are all 0s, whereas the data about the LPU's CPU usage is correct.
Search the MIB node 188.8.131.52.184.108.40.206.220.127.116.11 for the board node ID corresponding to the entity name.
In the MIB node 18.104.22.168.4.1.2011.5.25.31.22.214.171.124.5, search for the return value corresponding to the board node ID.
The returned values of MPU 9, MPU 10, SRU 9, and SRU 10 are all 0s, whereas those of CR56RPUA 9 and CR56RPUA 10 are 4 and 6, respectively. Log in to the NE40E-X8 and check the CPU usage of the device. The CPU usage of MPU 9 is 4, and that of MPU 10 is 6, which corresponds to the values returned from the CR56RPUA node.
The MIB entity name of the MPU of the NE40E-X8 series routers is CR56RPUA, and correct data can be collected only when you use the entity name for data search. The entity name used by the customer for data search is MPU. Therefore, incorrect data is returned.
Nodes and instance names in the MIB are not closely related to the software and hardware versions. If a similar problem occurs, perform the preceding steps for troubleshooting.
