Configuration procedure
NOTE:
Before you make the configuration, make sure the devices can reach each other.
1. Configure Device B.
# Enable the NQA server, and configure a listening service to listen to IP address 10.2.2.2 and UDP port
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.
<DeviceA> system-view
[DeviceA] nqa entry admin test
[DeviceA-nqa-admin-test] type voice
# Configure voice probe packets to use 10.2.2.2 as the destination IP address and port 9000 as the
destination port.
[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
# Start voice tests.
[DeviceA] nqa schedule admin test start-time now lifetime forever
# Stop the voice tests after a period of time.
[DeviceA] undo nqa schedule admin test
# Display the result of the last voice test.
[DeviceA] display nqa result admin test
