Diagnostic Port for Inter-Switch Link Testing in Electrical, Optical and Remote Loopback Modes

摘要

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. The ports will then be used to send test frames to perform the diagnostic tests.

1. A device comprising:
a processor; a media interface module; and a network port coupled to the processor and the media interface module; wherein the media interface module is configured to:
receive a command to perform an electrical loopback test after entering a diagnostic mode;receive incoming electrical signals for the electrical loopback test from the processor;perform a loopback of the incoming electrical signals;receive a second command to perform an optical loopback test after completing the electrical loopback test;receive incoming optical signals for the optical loopback test from a second media interface module; andperform a loopback of the incoming optical signals.
