Possible Cause Judgment Criterion Troubleshooting Method
The ONU functions
improperly or is faulty.
Run the ont reset command to
reset the ONU. It is found that
the ONU fails to recover its
configurations.
Replace the faulty ONU with a
functional one.
Step 5 Record the results of the preceding steps in the form for reporting a fault (see Fault Report Form),
fill out the entire form, and then submit the form to Huawei for technical support (see Contacting
Huawei for Assistance).
Step 6 End.

GPON ONU Profile Match state is Mismatch
An ONU connected to a GPON port of an OLT can go online successfully, but the queried
Match state of the ONU is displayed as mismatch by running the display ont info command
on the OLT.
Location Method
NOTE
Match state indicates the consistency between the actual ONU capabilities and the capability set (including
the port type and port quantity) configured in the ONU profiles. If an inconsistency exists, Match state is
displayed as mismatch.
In practice, ONUs in the offline state are bulk pre-configured on the OLT to facilitate service provisioning.
An ONU service profile and an ONU line profile are specified during such configurations. The ONU
profiles together can be regarded as a virtual ONU. Subsequent services are configured based on this virtual
ONU. Inconsistency between the capability set configured in the ONU profiles and the actual ONU
capabilities involves the following two situations:
l The configured capability set outmatches the actual ONU capabilities. If the ONU is bound to such
ONU profiles, ONU configurations will fail to be recovered when the ONU goes online.
l The configured capability set undermatches the actual ONU capabilities. In this case, the ONU
capabilities that are not covered by the ONU profiles will fail to be configured or applied.
When the queried Match state of the ONU is displayed as mismatch, locate the fault according
to the following procedure:
1. Check whether the capability set configured in the ONU line profile matches the actual
ONU capabilities.
CAUTION
To facilitate fault report, save the results of the following steps.
Procedure
Step 1 Run the display ont capability command to query the actual ONU capabilities. According to
the data plan, modify the current ONU profiles, or bind matching ONU profiles to the ONU.
