frame that was sent by the ASIC matches the test frame that was received. This test requires that the port be in diagnostics mode, and therefore disrupts communication. • External is a disruptive test that verifies port circuitry. The SFP level test sends a test frame from the ASIC through the SerDes chip, through the SFP transceiver fitted with an external loopback plug, and back to the ASIC for the selected ports. The port passes the test if the test frame that was sent by the ASIC matches the test frame that was received. This test requires that the port be in diagnostics mode. • Online is a non-disruptive test that 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, and therefore, does not disrupt communication. The port passes the test if the frame that was sent by the ASIC matches the frame that was received. NOTE: The online port diagnostic test is not allowed on a TR_Port. If attempted, an error message is displayed stating that an online port diagnostic test is not allowed on a TR port. Figure 51 Port Diagnostics dialog box To test a port: 1. Select one or more ports In the faceplate display. 2. Select Port > Port Diagnostics. 3. Choose one of the following options: • Select Online Port Diagnostics to open the Port Diagnostics dialog box.
