Zusammenfassung:	A diagnostic testing utility is used to perform single link diagnostics tests including an electrical loopback test, an optical loopback test, and a link traffic test. To perform the diagnostic tests, two ports at each end of a link are identified and configured as D_Ports and as such will be isolated from the fabric with no data traffic flowing through them. Advertisement frames may be sent at predetermined time intervals to transition the two ports to different states within the diagnostic test. After transitioning to the different states, the ports will then be used to send test frames to perform the diagnostic tests.
