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.

The NQA client also functions as the TCP client.

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

  - 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
