124CHAPTER 10: USING QOS MONITORING
Monitoring
ParametersThe VCX Call Processor is where you set the default threshold values for the statistics you want to gather and where you specify the 3Com IP phones (endpoints) that you want to monitor.
The monitoring parameters and phones specified for monitoring are persistent across system reboots and upgrades.
Use the QoS Monitoring Configuration tab to set the default threshold values for the following statistics:
■Computed Mean Opinion Score (MOS) average
■Jitter average
■Packet Loss average
■Round Trip Delay average
The thresholds configured here automatically become the defaults for any endpoints or subnets you add for monitoring. These settings can be overridden on a phone or subnet basis by editing the appropriate column in the QoS Monitored Endpoints table.
To set QoS Monitoring parameters:
1From the EMS client Explorer tree, select the 3Com VCX Call Processor.
2From the Properties tab, click the QOS Monitor Configuration tab.
3Enter threshold values for each statistic.
Monitored phones send QoS reports to the Call Processor when any threshold is breached.
Specifying Phones for Use the QoS Monitored Endpoints tab to specify which phones or set of QoS Monitoring phones report QoS statistics to the Call Processor.
The Call Processor only processes statistics from phones that are specified for monitoring. If monitored phones are setup on the primary and secondary Call Processor, only the Call Processor that the phone is currently specified to will receive the QoS reports from the phones.
To specify phones for QoS Monitoring:
1From the EMS client Explorer tree, select the 3Com VCX Call Processor.
2From the Properties tab, click the QOS Monitored Endpoints tab.
