between Device A and Device B. 

Figure 1-12 Network diagram for voice tests 

 

 

Configuration procedure 

1)  Configure Device B 

# Enable the NQA server and configure the listening IP address as 10.2.2.2 and port number as 9000. 

<DeviceB> system-view 

[DeviceB] nqa server enable 

[DeviceB] nqa server udp-echo 10.2.2.2 9000 

2)  Configure Device A 

# Create a voice test group and configure related test parameters. 

<DeviceA> system-view 

[DeviceA] nqa entry admin test 

[DeviceA-nqa-admin-test] type voice 

[DeviceA-nqa-admin-test-voice] destination ip 10.2.2.2 

[DeviceA-nqa-admin-test-voice] destination port 9000 

[DeviceA-nqa-admin-test-voice] quit 

# Enable voice test. 

[DeviceA] nqa schedule admin test start-time now lifetime forever 

# Disable the voice test after the test begins for a period of time. 

[DeviceA] undo nqa schedule admin test
