Unable to configure VAS profile because of missing configuration on Huawei OLT

Issue Description

Customers try to configure VAS profile for ONT like Huawei HG8310M, HG8326R through U2000, but task doesn't start, after some time, it times out and fail.
U2000 V100R002C01SPC100
MA5600T V800R006C02SPC100
ONT HG850a V100R007SPC008

Alarm Information

Null.

Handling Process

1. Check FTP account on Huawei OLT, it was not set, so I set it to be similar to that on U2000.
FTP must be set on OLT as it will download XML file from U2000 then configure ONT through OMCI.
2. Check SNMP parameters on OLT HUAWEI MA5683T , found trap port set to 161, it should be set to 162.
Traps must be configured correctly as OLT will report to U2000 the status of XML file transfer.
Test again, problem solved and VAS can be configured.

Root Cause

Causes of such case are:
1. FTP is not set on OLT such as Huawei MA5683T
2. SNMP parameters are not configured correctly between OLT & U2000.
