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

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
