UDP echo operation configuration example
Network requirements
As shown in
, 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 16 Network diagram
Configuration procedure
1.
Assign IP addresses to interfaces, as shown in
. (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.
