Aruba’s Approach to Lync over Wi-Fi
Manageability
Detailed diagnostics and monitoring data
helps the IT team to manage, monitor and
troubleshoot Lync over the Aruba Wi-Fi
•
Information on the system and AP
utilization for Lync
•
Centralized view of real time data on the
call – caller, callee, R-value, packet loss,
jitter etc
•
Co-relate call quality with client Wi-Fi
health metrics
•
Historical call quality information for the
AP and the users
•
Real time information about other active
sessions on the device for the user
•
Identify call roaming events, tagging
errors, device population
