Test Command
Tests ports using internal (SerDes level), external (transceiver), and online loopback tests. Internal and external tests require that the port be placed in diagnostic mode. Refer to the “Set Command” on page

Syntax | test |
| port [port_number] [test_type] |

| status |
Keywords | port [port_number] [test_type] |
| Tests the port given by [port_number] using the test given by [test_type]. If you |
| omit [test_type], Internal is used. [test_type] can have the following values: |
| internal |
| Tests the SerDes for all port speeds independent of the capabilities of the |
| transceiver. This is the default. The port must be in diagnostics mode to |
| perform this test. |
| external |
| Tests both the SerDes and transceiver for all port speeds that are supported |
| by the transceiver. The port must be in diagnostics mode to perform this test, |
| and a loopback plug must be installed in the transceiver. |
| online |
| Tests communications between the port and its device node or device loop |
| at the operating port speed. The port being tested must be online and |
| connected to a remote device. The port passes if the test frame that was |
| sent by the ASIC matches the frame that is received. This test does not |
| disrupt communication on the port. |
| cancel |
| Cancels the online test in progress. |
| status |
| Displays the status of a test in progress, or if there is no test in progress, the |
| status of the test that was executed last. |
Examples To run an internal or external port test, do the following:
1. To start an admin session, enter the following command and press the Enter key.

2.Place the port in Diagnostics mode, enter the following command (x = port number) and press the Enter key.
