Hi, I strongly doubt that the stripped down Comware 7 OS based HPE OfficeConnect 1950 Switch series is capable to support NQA features (Note that NQA - Network Quality Analyzer - is a feature that allows you to measure network performance, verify the service levels for IP services and applications, and troubleshoot network problems).
I saw NQA referenced only on mid/high-level full featured Comware 7 based HPE FlexFabric Switch Series (such as 59xx and 7900)...not on entry level (better, stripped down...from the features support standpoint) Switch Series such as the HPE OfficeConnect 1950 which can't exactly be compared to HPE FlexFabrics.
