Configuring a UDP Echo Test
A UDP echo test is used to test the connectivity and roundtrip time of a UDP echo packet from the client
to the specified UDP port on the NQA server.
Configuration prerequisites
A UDP echo test requires cooperation between the NQA server and the NQA client. The UDP listening
function needs to be configured on the NQA server before the UDP echo test. For the configuration of
the UDP listening function, refer to Configuring the NQA Server .
