crossPortTest
At each pass, a different data type is used to create the frame from a palette of seven types meaning that
if a pass of seven is requested, seven different frames are used in the test. If eight passes, the first seven
frames are unique, and the eighth is the same as the first. The data palette of seven are:
CSPAT:
BYTE_LFSR:
CHALF_SQ:
QUAD_NOT:
CQTR_SQ:
CRPAT:
RANDOM:

In online mode (in which the switch is enabled prior to executing the
ports that are cable loopbacked to ports in the same switch are tested. Ports connected outside of the
switch are ignored.
To run the

of the following message is displayed:
Need at least 1 port(s) connected to run this test.
Need at least 2 port(s) cross-connected to run this test.
In offline mode (when the switch is disabled prior to executing the
are assumed to be cable loopbacked to different ports in the same switch. If one or more ports are not
connected, the test aborts.
Note
All ports must be connected using loopback plugs or loopback cables for this test to run correctly in
offline mode.
The test determines which port is connected to which port transmitting frames. If any ports are not
properly connected (improperly seated SFPs or cables, bad SFPs or cables, or improper connection or
improper connection of SWL to LWL), the following message is displayed:
One or more ports is not active, please double check
fibre channel connections on all ports.
Since this test includes the media and the fiber cable in its test path, its results combined with the results
of portLoopbackTest
It is also possible to use loopback modes 3 and 5 to further isolate failures; refer to -lb_mode, below.

command behavior depends on the modes activated.
crossPortTest command successfully the test must find at least one port (-lb_mode = 1, this
and spinSilk can be used to determine which components of the switch are faulty.
Specify the number of frames to send. The test will progress until the specified
number of frames has been transmitted on each port. The default value is 10.
Specify the loopback mode for the test. By default,
port loopback. Valid values are:
0 Cable loopback
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
