That is correct, you need AirWave running 8.2.3.1 and InstanOS minimum version 6.5.1.0-4.3.1.0 (Early Release).
Extract from the latest Release Note:
Clarity Live
Instant now supports inline monitoring through Clarity Live to identify client connectivity issues and send the data to AirWave for analysis. It helps in isolating the root cause of the connectivity issues experienced by receiving regular statistics and updates generated by the events. For more information, see:
- Clarity Live in Aruba Instant 6.5.1.0-4.3.1.0 User Guide.
- Clarity,show clarity config, and show clarity history in Aruba Instant 6.5.1.0-4.3.1.0 CLI Reference Guide.
But, I would recommand to use the latest EA version 6.5.1.0-4.3.1.2 as per discussion with my local SE who contributed to debug some stuff in previous version...
