Number of million frames to send. The test will progress
until the specified number of frames has been transmitted
on each port. The default value for nmill is 10, so the
number of frames sent will be at least 10 million. The
counting is not exact so the actual number of frames sent
will tend to be slightly larger, particularly at 2-Gbps link
speeds.
Specify the first port to test, if omitted 0 will be used. This
operand is optional.
Specify the last port to test. The test will be performed on
ePortBeg to ePortEnd inclusive. If ePortEnd is omitted then
the default will be to test all ports. This operand is
optional.
This parameter may be used to cause spinfab to mark
failing ports as bad like a normal diagnostic.
1 = Mark failing ports as BAD
0 = do not mark failed ports as bad.
To minimize the impact on live fabrics this test normally
logs errors, but does not set the port status to FAILED. This
parameter is provided to force the failing ports to be
marked as BAD, in the same manner as other diagnostics.
In test or qualification environments without live traffic this
may be useful with large values of nmil. This mode is
disabled by default.
Specify the number of frames to send in millions. The test
will progress until the specified number of frames has
been transmitted on each port. The default value is 10,
that is, 10 million frames. This command only
approximately counts the frames and the actual number of
frames sent will be slightly larger, particularly at 2G link
speeds.
Specify a list of user ports to test. By default all of the ISL
ports in the current switch will be tested. This option may
be used to restrict testing to the specified ports. This
operand is optional. See the itemlist command for
more information.
