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. This is the default. The port must be in diagnostics
mode to perform this test.
external —Tests both the SerDes and 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.
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.
