The output shows that it took Device A 64 milliseconds to obtain data from the HTTP server.
UDP jitter operation configuration example
Network requirements
As shown in Figure 42, configure a UDP jitter operation to test the jitter, delay, and round-trip time
between Device A and Device B.
Figure 42 Network diagram
Configuration procedure
1. Assign IP addresses to interfaces, as shown in Figure 42. (Details not shown.)
2. Configure static routes or a routing protocol to make sure the devices can reach each other.
(Details not shown.)
3. Configure Device B:
# Enable the NQA server.
<DeviceB> system-view
[DeviceB] nqa server enable
# Configure a listening service to listen on the IP address 10.2.2.2 and UDP port 9000.
[DeviceB] nqa server udp-echo 10.2.2.2 9000
4. Configure Device A:
# Create a UDP jitter operation.
<DeviceA> system-view
[DeviceA] nqa entry admin test1
[DeviceA-nqa-admin-test1] type udp-jitter
# Specify 10.2.2.2 as the destination address of the operation.
[DeviceA-nqa-admin-test1-udp-jitter] destination ip 10.2.2.2
# Set the destination port number to 9000.
[DeviceA-nqa-admin-test1-udp-jitter] destination port 9000
# Configure the operation to repeat every 1000 milliseconds.
[DeviceA-nqa-admin-test1-udp-jitter] frequency 1000
[DeviceA-nqa-admin-test1-udp-jitter] quit
# Start the UDP jitter operation.
[DeviceA] nqa schedule admin test1 start-time now lifetime forever
# After the UDP jitter operation runs for a period of time, stop the operation.
[DeviceA] undo nqa schedule admin test1
# Display the most recent result of the UDP jitter operation.
[DeviceA] display nqa result admin test1
NQA entry (admin admin, tag test1) test results:
Send operation times: 10 Receive response times: 10
Min/Max/Average round trip time: 15/32/17
Square-Sum of round trip time: 3235
