UDP echo operation configuration example
Network requirements
As shown in Figure 45, configure a UDP echo operation on the NQA client to test the round-trip time
to Device B. The destination port number is 8000.
Figure 45 Network diagram
Configuration procedure
1. Assign IP addresses to interfaces, as shown in Figure 45. (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 8000.
[DeviceB] nqa server udp-echo 10.2.2.2 8000
4. Configure Device A:
# Create a UDP echo operation.
<DeviceA> system-view
[DeviceA] nqa entry admin test1
[DeviceA-nqa-admin-test1] type udp-echo
# Specify 10.2.2.2 as the destination IP address.
[DeviceA-nqa-admin-test1-udp-echo] destination ip 10.2.2.2
# Set the destination port number to 8000.
[DeviceA-nqa-admin-test1-udp-echo] destination port 8000
# Enable the saving of history records.
[DeviceA-nqa-admin-test1-udp-echo] history-record enable
[DeviceA-nqa-admin-test1-udp-echo] quit
# Start the UDP echo operation.
[DeviceA] nqa schedule admin test1 start-time now lifetime forever
# After the UDP echo operation runs for a period of time, stop the operation.
[DeviceA] undo nqa schedule admin test1
# Display the most recent result of the UDP echo operation.
[DeviceA] display nqa result admin test1
NQA entry (admin admin, tag test1) test results:
Send operation times: 1 Receive response times: 1
Min/Max/Average round trip time: 25/25/25
Square-Sum of round trip time: 625
Last succeeded probe time: 2011-11-22 10:36:17.9
Extended results:
Packet loss ratio: 0%
