Configuration procedure
Before you make the configuration, make sure the devices can reach each other.
1) Configure Device
# Enable the NQA server and configure a listening service to listen to IP address 10.2.2.2 and UDP port
9000.
<Device> system-view
[Device] nqa server enable
[Device] nqa server udp-echo 10.2.2.2 9000
2) Configure AC
# Create a UDP jitter test group.
<AC> system-view
[AC] nqa entry admin test
[AC-nqa-admin-test] type udp-jitter
# Configure UDP jitter packets to use 10.2.2.2 as the destination IP address and port 9000 as the
destination port.
[AC-nqa-admin-test-udp-jitter] destination ip 10.2.2.2
[AC-nqa-admin-test-udp-jitter] destination port 9000
# Configure the device to perform UDP jitter tests at an interval of 1000 milliseconds.
[AC-nqa-admin-test-udp-jitter] frequency 1000
[AC-nqa-admin-test-udp-jitter] quit
# Start UDP jitter tests.
[AC] nqa schedule admin test start-time now lifetime forever
# Stop UDP jitter tests after a period of time.
[AC] undo nqa schedule admin test
# Display the result of the last UDP jitter test.
[AC] display nqa result admin test
