124 CHAPTER 10: USING QOS MONITORING
VCX Call Processor The 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.
Setting QoS
Monitoring
Parameters
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:
1 From the EMS client Explorer tree, select the 3Com VCX Call Processor.
2 From the Properties tab, click the QOS Monitor Configuration tab.
3 Enter threshold values for each statistic.
Monitored phones send QoS reports to the Call Processor when any
threshold is breached.
Specifying Phones for
QoS Monitoring
Use the QoS Monitored Endpoints tab to specify which phones or set of
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:
1 From the EMS client Explorer tree, select the 3Com VCX Call Processor.
2 From the Properties tab, click the QOS Monitored Endpoints tab.
