■ Internal — a disruptive test that verifies port circuitry. The SerDes level test
sends a test frame from the ASIC through the SerDes chip and back to the
ASIC for the selected ports. The port passes the test if the frame that was sent
by the ASIC matches the test frame that was received. This test requires that
the port be in diagnostics mode.
■ External — 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.
