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] Availability admin 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 the 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 port M's transmitter, and looping the frames back through an external fiber cable into port M's receiver, thus exercising all the switch components from the main board, to the fiber 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. The following port types are supported: • E_Ports • F_Ports (must support ELS ECHO) • L_Ports • N->N loopback ports This command will not run on any other port type. The command performs the following actions: 1. Initiate tests on certain ports (portTest command). 2. Stop active tests on certain ports (stopPortTest command). 3. Get the snapshot of the test result (portTestShow command). Once portTest is triggered, you can use stopPortTest to stop the test. See the stopPortTest command for more information. View the current progress of portTest by running portTestShow. See the portTestShow command for more information. If there is a port type change during portTest execution, the test will continue 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 will start a new test using the new port type to start a appropriate test. 526 Fabric OS commands
