OLT GPON port showing Unknow status in U2000
device type: MA5608T
version: V8R17C00
U2000 version: V2R17C50
when customer check on HUAWEI OLT MA5608T, they found the GPON port showing unknown status from U2000, and cannot create any service for it
Handling Process
after we check and doing the synchronize , the issue still exist, and we check from the device configuration file , we found the customer configure the ifindex standard
Analyze the MIB node response received by the NMS and find that the result is “no such instance”
synchronize succeed and no error
found from the configuration file , the customer has configured the ifindex standard
Root Cause
The cause is that the MIB switch is configured on the device. snmp-agent ifindex-format standard
In this case, if the value of ifindex is not within the range of interger32, the value of iftype in ifindex is converted to a smaller value. This ensures that the value range of ifindex is within the range of interger32, which complies with the value range of ifindex defined in the standard. However, this requires the cooperation of the upper-layer OSS
Solution
If there no such requirement , the ifindex in the standard format no need to configured . For example, the U2000 connected to the device does not use this coding scheme,
Then you can shut it down.
Verify that the value can be obtained after the modification.
Suggestions
In addition, recommended to configure this switch and check whether it is required by a third-party OSS. If yes, you can configure this parameter. However, you are advised to specify the IP address so that other NMSs are not affected.
The configuration is similar to this configuration.
