Node-to-Node (online) — the Node-to-Node test verifies communications between the port and its device node or device loop. The port being tested must be online and connected to a remote device. The port passes the test if the frame that was sent by the ASIC matches the frame that was received. This test does not disrupt communication on the selected port. This test requires that the port be online, and therefore, does not disrupt communication.

To run the internal, external, or online port loopback test on a port, perform the following procedure:

1.Select the port to be tested in the faceplate display.

2.Select Port > Port Loopback Test to open the Port Loopback Test dialog.

3.Select Internal, External, or Online in the Test Selection area.

4.Click OK and McDATA Web Server will change the port state. If you choose Internal or External, McDATA Web Server will prompt you to confirm that the port state needs to be changed to the diagnostic state. If you selected External, verify a loopback plug has been installed.

5.Enter the frame count, frame size, and select a test pattern option. You may use the default pattern or enter an 8-digit pattern (hex). Select Terminate Test Upon Error for online test, if you want the test to stop should it encounter an error.

6.Click Start Test to begin the test. The Test Results area displays the test status, number of frames sent, and number of errors found.

7.To test another port, open the Select Port drop-down list and select another port (number) and test type (Internal, External, or Online) in the Test Selection area.

8.Click Start Test to begin the next test. Observe the results in the Test Results area.
