Porttest - Brocade Communications Systems Brocade 8/12c Command Reference Manual

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 in a single replaceable element and to trace problems to
near-end terminal equipment, far-end terminal equipment, or the transmission line. You can
perform this test on a daily basis or as needed to verify the persistence of failures detected earlier.
This command verifies the functional operation of the switch by sending frames from a port's
transmitter, and looping the frames back through an external fiber cable into the port's receiver.
The test exercises all 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 type: a short-wavelength media (switch)
port should be connected to another short-wavelength media (device) port using a
short-wavelength cable; a long-wavelength port should be connected to a long-wavelength port,
and a copper port should be connected to a copper port.
Only one frame is transmitted and received at any given time. The port LEDs flicker green while the
test is running.
This command supports E_Ports, F_Ports (must support ELS Echo), L_Port, and N->N loopback
ports. In addition, on switches running Fabric OS v6.4.0 and later, you can now use portTest on
port configurations that previously caused nonspecific test results or were skipped by portTest. The
following ports are now support the portTest diagnostics.

This command performs the following operations:
1. Initiates tests on certain ports (portTest command).
2. Stops active tests on certain ports (stopPortTest command).
3. Takes a snapshot of the test result (portTestShow command).
Use the stopPortTest command to stop the test. Refer to the stopPortTest help page for more
information.
