Verifying Network Connectivity in Client Mode Using the Network Test Tool

You can run the tool in client mode to check the quality of the network connectivity between two client computers and to measure the bandwidth utilization for data transfer.

When the tool runs in client mode, the client where you run the tool (source client) attempts to initiate a connection with a client that you designate as the listening server. After the connection is established, the source client sends buffers to the listening server to verify data transmission. During the connectivity check, you can also specify parameters for data transmission, such as the buffer count and buffer delay.

On Windows clients, the tool runs as a graphical user interface. On UNIX, Linux, and Macintosh clients, the tool runs as a menu-driven interface.

Procedure

Follow the steps that correspond to the operating system of your client.

On Windows

1. Go to the Software_Installation_Directory/Base directory and double-click CVNetworkTestTool.

   The Network Test Tool dialog box appears.

2. On the Network Check tab, click Client to run the tool in client mode.

3. In the Input section, type the host name and client name of the listening server.

   Note: By default, server port 25000 is used to communicate control information with the source client. You can provide a different port number.

4. If you want to modify the data transmission options, click Settings. In the Client Settings window, update the necessary options:

   • In the First Buffer Delay box, type the number of seconds to wait before sending or receiving the first buffer. The default delay is 0 seconds.

   • In the Inter Buffer Delay box, type the number of milliseconds to wait before sending or receiving each buffer. The default delay is 0 milliseconds.

   • In the Buffer Size Server to Client box, type the number of bytes to transmit from the listening server to the source client. The default client-to-server buffer size is 16 KB.

   • In the Buffer Size Client to Server box, type the number of bytes to transmit from the source client to the listening server. The default server-to-client buffer size is 16 KB.

   • In the Buffer Count box, type the number of buffers of random data to send or receive from the listening server. The default buffer count is 10000.

5. Click the play button to start the connectivity check.

   Tip: During the connectivity check, you can stop or pause the data transmission by clicking the stop button.

   The tool displays the following results:

   • The Output section displays the network connectivity checks as well as the data transfer details.

   • The Test Port Details section displays the TCP/IP protocol used for the connection as well as the bandwidth utilization (throughput) during the data transfer.

   • The Log section displays the log details of the connectivity check. You can copy and paste the log contents.

On UNIX, Linux, and Macintosh

1. At the command prompt, go to the Software_Installation_Directory/Base directory and run the following command:

   ./CvNetworkTestTool

   A list of menu options appear for the Network Test tool.

2. In the Choose Mode section, enter 3 and press Enter.

3. If you want to modify the data transmission options, locate the Advanced Settings section and perform one or more of the following steps:

   • To specify the client name of the listening server, enter 4 and press Enter.

   • To specify a different server port number to communicate control information with the source client, enter 5 and press Enter. The default port number is 25000.

   • To specify the number of seconds to wait before sending or receiving the first buffer, enter 6 and press Enter. The default delay is 0 seconds.

   • To specify the number of milliseconds to wait before sending or receiving each buffer, enter 7 and press Enter. The default delay is 0 milliseconds.

   • To specify the number of bytes to transmit from the listening server to the source client, enter 8 and press Enter. The default client-to-server buffer size is 16 KB.

   • To specify the number of bytes to transmit from the source client to the listening server, enter 9 and press Enter. The default server-to-client buffer size is 16 KB.

   • To specify the number of buffers of random data to send or receive from the listening server, enter 10 and press Enter. The default buffer count is 10000.

4. In the Client Mode Menu section, enter 1 and press Enter.

5. Enter the host name or IP address of the listening server and press Enter.

   Tip: During the connectivity check, you can stop or pause the data transmission by pressing the Esc key.

   The tool displays the network connectivity results, such as the data transfer details and the bandwidth utilization (throughput).

6. If you want to perform another operation, enter y and press Enter. To exit the tool, enter n and press Enter.
