UDP Jitter Test Configuration Example
Network requirements
As shown in Figure 8 , use the NQA UDP jitter function to test the delay jitter of packet transmission
between Device A and Device B.
Figure 8 Network diagram for UDP jitter tests
Configuration procedure
Step1 Configure Device B
# Enable the NQA server and configure the listening IP address as 10.2.2.2 and port number as 9000.
system-view
[DeviceB] nqa server enable
[DeviceB] nqa server udp-echo 10.2.2.2 9000
Step2 Configure Device A
# Create a UDP jitter test group and configure related test parameters.
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
Square-Sum of round trip time: 3235
Last succeeded probe time: 2008-05-29 13:56:17.6
Extended results:
Packet loss in test: 0%
Failures due to timeout: 0
Failures due to disconnect: 0
Failures due to no connection: 0
Failures due to sequence error: 0
