# Display the history records of the TCP operation.
[DeviceA] display nqa history admin test1
NQA entry (admin admin, tag test1) history records:
Index Response Status Time

The output shows that it took Device A 13 milliseconds to establish a TCP connection to port
9000 on the NQA server.
UDP echo operation configuration example
Network requirements
As shown in Figure 46, configure a UDP echo operation to test the round-trip time between Device A
and Device B. The destination port number is 8000.
Figure 46 Network diagram
Configuration procedure
1. Assign each interface an IP address. (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 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
# Configure 10.2.2.2 as the destination IP address and port 8000 as the destination port.
[DeviceA-nqa-admin-test1-udp-echo] destination ip 10.2.2.2
[DeviceA-nqa-admin-test1-udp-echo] destination port 8000
# Enable the saving of history records.
