UDP jitter test configuration example
Network requirements
As shown in Figure 12 , configure NQA UDP jitter tests to test the delay jitter of packet transmission
between Device A and Device B.
Figure 12 Network diagram
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.
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.
system-view
[DeviceA] nqa entry admin test
[DeviceA-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.
[DeviceA-nqa-admin-test-udp-jitter] destination ip 10.2.2.2
[DeviceA-nqa-admin-test-udp-jitter] destination port 9000
# Configure the device to perform UDP jitter tests at an interval of 1000 milliseconds.
[DeviceA-nqa-admin-test-udp-jitter] frequency 1000
[DeviceA-nqa-admin-test-udp-jitter] quit
# Start UDP jitter tests.
[DeviceA] nqa schedule admin test start-time now lifetime forever
# Stop UDP jitter tests after 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
