Viewing VoWLAN Metrics
VoWLAN metrics provide you with diagnostic information pertinent to VoIP performance. This
information helps you determine whether problems are being introduced by the WLAN or the wired
network. VoWLAN metrics are stored on WLSE.
Note The WLSE updates VoWLAN metrics every 90 seconds and stores metrics for up to 1.5 hours.
