UDP Jitter Test Configuration Example
Network requirements
Use the NQA UDP jitter function to test the delay jitter of packet transmission between Device A and
Device B.
Figure 1-7 Network diagram for UDP jitter 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 UDP jitter test group and configure related test parameters.
<DeviceA> system-view
[DeviceA] nqa entry admin test
[DeviceA-nqa-admin-test] type udp-jitter
[DeviceA-nqa-admin-test-udp-jitter] destination ip 10.2.2.2
[DeviceA-nqa-admin-test-udp-jitter] destination port 9000
[DeviceA-nqa-admin-test-udp-jitter] frequency 1000
[DeviceA-nqa-admin-test-udp-jitter] quit
# Enable UDP jitter test.
[DeviceA] nqa schedule admin test start-time now lifetime forever
# Disable UDP jitter test after the test begins for a period of time.
[DeviceA] undo nqa schedule admin test
# Display the result of the last UDP jitter test.
[DeviceA] display nqa result admin test
NQA entry(admin admin, tag test) test results:
Destination IP address: 10.2.2.2
Send operation times: 10 Receive response times: 10
Min/Max/Average round trip time: 15/32/17
