The display nqa history command cannot show you the results of UDP jitter tests. Therefore, to know
the result of a UDP jitter test, you are recommended to use the display nqa result command to view
the probe results of the latest NQA test, or use the display nqa statistics command to view the
statistics of NQA tests.
SNMP Test Configuration Example
Network requirements
Use the NQA SNMP query function to test the time it takes for Device A to send an SNMP query packet
to the SNMP agent and receive a response packet.
