UDP echo test configuration example

Network requirements

As shown in Figure 42, configure NQA UDP echo tests to test the round-trip time between LB module and

Device. The destination port number is 8000.

Configuration procedure

NOTE:

Before you make the configuration, make sure the devices can reach each other.

1. Configure Device

# Enable the NQA server and configure a listening service to listen to IP address 10.2.2.2 and UDP port

8000.

<Device> system-view

[Device] nqa server enable

[Device] nqa server udp-echo 10.2.2.2 8000

2. Configure LB

# Create a UDP echo test group.

<LB> system-view

[LB] nqa entry admin test

[LB-nqa-admin-test] type udp-echo

# Configure UDP packets to use 10.2.2.2 as the destination IP address and port 8000 as the destination

port.

[LB-nqa-admin-test-udp-echo] destination ip 10.2.2.2

[LB-nqa-admin-test-udp-echo] destination port 8000

# Enable the saving of history records.

[LB-nqa-admin-test-udp-echo] history-record enable

[LB-nqa-admin-test-udp-echo] quit

# Start UDP echo tests.

[LB] nqa schedule admin test start-time now lifetime forever

# Stop UDP echo tests after a period of time.

[LB] undo nqa schedule admin test

# Display the results of the last UDP echo test.

[LB] display nqa result admin test

NQA entry (admin admin, tag test) test results:

Destination IP address: 10.2.2.2

Send operation times: 1 Receive response times: 1

Min/Max/Average round trip time: 25/25/25
