TCP operation configuration example

As shown in Figure 15, configure a TCP operation to test the time required for Device A to establish a TCP connection with Device B.

1. Assign IP addresses to interfaces, as shown in Figure 15. (Details not shown.)

2. Configure static routes or a routing protocol to make sure the devices can reach each other. (Details not shown.)

3. Configure Device B:

   # Enable the NQA server.

   <DeviceB> system-view
   [DeviceB] nqa server enable
   

   # Configure a listening service to listen on the IP address 10.2.2.2 and TCP port 9000.

   [DeviceB] nqa server tcp-connect 10.2.2.2 9000
   

4. Configure Device A:

   # Create a TCP operation.

   <DeviceA> system-view
   [DeviceA] nqa entry admin test1
   [DeviceA-nqa-admin-test1] type tcp
   

   # Specify 10.2.2.2 as the destination IP address.

   [DeviceA-nqa-admin-test1-tcp] destination ip 10.2.2.2
   

   # Set the destination port number to 9000.

   [DeviceA-nqa-admin-test1-tcp] destination port 9000
   

   # Enable the saving of history records.

   [DeviceA-nqa-admin-test1-tcp] history-record enable
   [DeviceA-nqa-admin-test1-tcp] quit
   

   # Start the TCP operation.

   [DeviceA] nqa schedule admin test1 start-time now lifetime forever
   

   # After the TCP operation runs for a period of time, stop the operation.

   [DeviceA] undo nqa schedule admin test1
   

   # Display the most recent result of the TCP operation.

   [DeviceA] display nqa result admin test1
   NQA entry (admin admin, tag test1) test results:
       Send operation times: 1              Receive response times: 1
       Min/Max/Average round trip time: 13/13/13
       Square-Sum of round trip time: 169
       Last succeeded probe time: 2011-11-22 10:27:25.1
     Extended results:
       Packet loss ratio: 0%
       Failures due to timeout: 0
       Failures due to disconnect: 0
       Failures due to no connection: 0
       Failures due to internal error: 0
       Failures due to other errors: 0
   

   # Display the history records of the TCP operation.

   [DeviceA] display nqa history admin test1
   NQA entry (admin admin, tag test1) history records:
     Index      Response     Status           Time
     1          13           Succeeded        2011-11-22 10:27:25.1
   

   The output shows that it took Device A 13 milliseconds to establish a TCP connection to port 9000 on the NQA server.
