NFA ver12 Question

Hi All,

Recently I installed the latest version12000 NFA for customer to analysis the traffic. So customer picked the core switch huawei and one cisco core switch to test it.
Then we found the NFA still show ifindex interface name after updating the snmp string for huawei switch. And we tried to run snmpwalk.bat to check these ifindex. These ifindex seem not exist. That's so weird. So we tried to edit the system_properties.conf file and add the line "SNMPTargetV2C=true" according to Forum. But it can't work.
Here is huawei core switch configuration and attached screen and snmpwalk result, we just configured two interfaces about inbound and outbound, but the NFA found 6 interfaces, but no one interface seems match 10GE1/0/1 OR 10GE2/0/1. Please give some advice, thx in advance!
