Hello, friend!
After the MDU goes online on the OLT, the MDU obtains the configuration information according to the configurations such as the line profile, SNMP profile, and management address that are bound to the MDU. If the MDU cannot be completely configured, a message is displayed indicating that the configuration fails.
In this case, check the following items:
1. Check whether the configuration issued by the OLT is correct and whether the parameter value exceeds the capability of the MDU.
2. Check whether the configuration conflicts with the MDU configuration.
3. Check whether the MDU fails to obtain the correct configuration due to poor line quality.
4. Check whether the MDU system is abnormal.
Thanks!
