portTest 2 portTest Performs a functional test of a switch in a live fabric. Synopsis porttest [-ports itemlist][-iteration count][-userdelay time][-timeout time][-pattern pattern] [-patsize size][-seed seed][-listtype porttype] Description Use this command to isolate problems to a single replaceable element and isolate problems to near-end terminal equipment, far-end terminal equipment, or transmission line. Diagnostics can be executed every day or on demand. This command verifies the intended functional operation of the switch by sending frames from a port's transmitter, and looping the frames back through an external fibre cable into the port's receiver, thus exercising all the switch components from the main board, to the fibre cable, to the media (of the devices and the switch), and back to the main board. The cables and media connected should be of the same technology: a short-wavelength media (switch) port is connected to another short-wavelength media (device) port using a short-wavelength cable; a long wavelength port is connected to a long-wavelength port, and a copper port is connected to a copper port. Only one frame is transmitted and received at a time. The port LEDs flicker green while the test is running. Only the following port types are supported: • E_Ports • F_Ports (must support ELS Echo) • L_Ports • N->N loopback ports This command performs the following operations: 1. Initiates tests on certain ports (portTest command). 2. Stops active tests on certain ports (stopPortTest command). 3. Gets the snapshot of the test result (portTestShow command). Once portTest is triggered, you can use stopPortTest to stop the test. Refer to the stopPortTest command for more information. View the current progress of portTest by running portTestShow. Refer to the portTestShow command for more information. If there is a port type change during portTest execution, the test continues on a given port as long as it can be supported and it is asked to do so. If a request was made to test all possible ports on a given switch, portTest starts a new test using the new port type to start an appropriate test. Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability" for details. Operands This command has the following operands: -ports itemlist Specify a list of user ports to test. By default, all the user ports in the switch are tested. Refer to itemList help pages for further details. Fabric OS Command Reference 539 53-1000599-02
