Configuring a TCP Test Instance

Configuring a TCP Test Instance

Context

Before configuring a TCP test instance, configure a TCP server and ensure reachable routes between the TCP client and the TCP server.

An NQA TCP test measures the speed at which a TCP connection can be set up between an NQA client and a TCP server through the three-way handshake.

NOTE:

The NQA client also functions as the TCP client.

The timeout, probe-count, frequency, and interval commands constrain each other; therefore, properly set the values when running the four commands. Improper command settings may lead to test failure.

  • On a network with poor quality and low transmission rate, increase the timeout value to ensure that the response to NQA detection packets can be received.
  • On a network with low reliability, increase the probe-count value because multiple detection packets may need to be sent to ensure successful detection.
  • The interval value must be larger than the timeout value.
  • The frequency value must be larger than the product of interval and probe-count.

Procedure

  • Configure the TCP server.
    1. Run system-view

      The system view is displayed.

    2. Run nqa-server tcpconnect [ vpn-instance vpn-instance-name ] ip-address port-number

      The monitoring IP address and port number of the TCP server are configured.

  • Configure the NQA client.
    1. Run system-view

      The system view is displayed.

    2. Run nqa test-instance admin-name test-name

      An NQA test instance is created, and the NQA view is displayed.

    3. Run test-type tcp

      The test type is set to TCP.

    4. Run destination-address ipv4 ipv4-address

      The destination IP address is configured.

    5. (Optional) Run the following commands as required to configure parameters for the TCP test.

      • Run description string

        A description is configured for the test instance.

      • Run frequency interval

        The test period is set for the NQA test instance.

      • Run timeout time

        The timeout period of a probe is set for the NQA test instance.

      • Run destination-port port-number

        The destination port number is configured.

      • Run source-address ipv4 ipv4-address

        The source IP address is configured.

      • Run source-port port-number

        The source port number is configured.

      • Run ttl number

        The TTL value in the NQA test packet is set.

      • Run sendpacket passroute

        The NQA test instance is configured to send packets without searching the routing table.

      • Run probe-count number

        The number of probes in a test is set.

      • Run tos value

        Type of Service (TOS) is set for the test packet.

      • Run fail-percent percent

        The failure percentage is set for the NQA test instance.

      • Run interval seconds interval

        The interval at which test packets are sent is configured.

      • Run vpn-instance vpn-instance-name

        The VPN instance name is configured.

      • Run records history number

        The maximum number of historical records is set for the NQA test instance.

      • Run records result number

        The maximum number of result records is set for the NQA test instance.

      • Run agetime hh:mm:ss

        The aging time is set for the NQA test instance.
