Configuration procedure
1) Configure Switch.
# Enable the NQA server and configure the listening IP address as 10.2.2.2 and port number as 9000.
<Switch> system-view
[Switch] nqa server enable
[Switch] nqa server udp-echo 10.2.2.2 9000
2) Configure AC.
# Create a UDP-jitter test group and configure related test parameters.
<AC> system-view
[AC] nqa entry admin test
[AC-nqa-admin-test] type udp-jitter
[AC-nqa-admin-test-udp-jitter] destination ip 10.2.2.2
[AC-nqa-admin-test-udp-jitter] destination port 9000
[AC-nqa-admin-test-udp-jitter] quit
# Enable the UDP-jitter test.
[AC] nqa schedule admin test start-time now lifetime forever
# Display results of a UDP-jitter test.
[AC] display nqa result admin test
