Hello, friend!
Confirmed:
The interoperability license only ensures that third-party ONTs can go online on Huawei OLTs. But it doesn't support Huawei OLT and NMSs configure services on third-party devices.
Therefore, the PPPoE configuration issued by the U2000 to the third-party ONT cannot take effect.
You can only manually configure services on third-party ONTs. The interworking license only ensures that ONT services can be transmitted.
Thanks!
