The output shows that the packets sent by Device A can reach Device B through Device C. No
packet loss occurs during the operation. The minimum, maximum, and average round-trip times are
2, 5, and 3 milliseconds, respectively.
ICMP jitter operation configuration example
Network requirements
As shown in Figure 37, configure an ICMP jitter operation to test the jitter between Device A and
Device B.
Figure 37 Network diagram
Configuration procedure
1. Assign IP addresses to interfaces, as shown in Figure 37. (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 A:
# Create an ICMP jitter operation.
<DeviceA> system-view
[DeviceA] nqa entry admin test1
[DeviceA-nqa-admin-test1] type icmp-jitter
# Specify 10.2.2.2 as the destination address for the operation.
[DeviceA-nqa-admin-test1-icmp-jitter] destination ip 10.2.2.2
# Configure the operation to repeat every 1000 milliseconds.
[DeviceA-nqa-admin-test1-icmp-jitter] frequency 1000
[DeviceA-nqa-admin-test1-icmp-jitter] quit
# Start the ICMP jitter operation.
[DeviceA] nqa schedule admin test1 start-time now lifetime forever
# After the ICMP jitter operation runs for a period of time, stop the operation.
[DeviceA] undo nqa schedule admin test1
# Display the most recent result of the ICMP 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: 1/2/1
Square-Sum of round trip time: 13
