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.
