Operation Manual – NQAH3C S3610&S5510 Series Ethernet Switches Chapter 1 NQA Configuration1-191.2.7 Configuring the TCP TestCaution:You are not recommended to perform an NQA TCP test on ports from 1 to 1023 (knownports). Otherwise, the NQA test will fail or the corresponding services of this port will beunavailable.The TCP test is used to test the TCP connection between the client and the specifiedserver and the setup time for the connection.The TCP test includes TCP-Public test and TCP-Private test.z For the TCP-Public test, a connection setup request is permanently initiated toTCP port 7 of the destination address. No destination port needs to be configuredon the client, but TCP port 7 used for listening needs to be configured on theserver. Even if a port is configured on the client, the port does not take effect.z For the TCP-Private test, a connection setup request is initiated to the specifiedport of the destination address.I.
