Abstract
A diagnostic testing utility is used to perform single link diagnostics tests including an electrical loopback test, an optical loopback test, a link traffic test, and a link distance measurement test. To perform the diagnostic tests, two ports at each end of a link are identified and then statically configured by a user. The ports will be configured as D_Ports and as such will be isolated from the fabric with no data traffic flowing through them. This configuration can be static or can be on request or on errors. The ports will then be used to send test frames to perform the diagnostic tests. After completion of requested or on error testing the ports can return to normal operation.
