Use this option with the external loopback test D3 to select a reference card. During the
external loopback test the physical loopback can be provided with a RJ45 loopback plug or
a CAT5 cable connected to a reference device (which loops back the data).
-lbe g:h:t
define the number of packets to use during external loopback
Selects the number of packets to send during the external loopback test D3 (g ,h ,t are the
gigabit, hundred megabit, and ten megabit packet counts respectively) (default values are
g=2000, h=1000, t=600). It is mandatory that all packets counts are entered with this
command line option.
-ckdev <xy>
executes diagnostic only x=chip rev and y=metal rev
If <xy> does not match the device being accessed diagnostics will not execute. Use this
option on a production line to verify that only chips of a specific rev are run with
diagnostics and all others fail.
-l200 <m200>
controls the number of 200 packets to send
This option is used for the D4, “1G False Carrier”, loopback test. During the test packets
are sent out in groups of 200. The user specified <m200> value determines the number of
200 packet groups to send out. The default value is <m200> =50 or 50 groups of 200
packets.
-disppkts
display the packet count during the progress of the test
This option is used for the D4, “1G False Carrier”, loopback test. On long-term test this
option is entered to display the packet count every 20,000 packets to let a user know the
test is operating normally and not frozen.
-dispgbend
display the packet count at the end of the test
This option is used for the D4, “1G False Carrier”, loopback test. This option is entered to
print out the final packet count at the end of the test.
-errlimit <lim>
controls the number of errors seen before the test fails
This option is used for the D4, “1G False Carrier”, loopback test. The default value is
<lim> =3.
-pktf0
packet data pattern is alternating 64 1’s and 0’s
This option is used for the D4, “1G False Carrier”, loopback test. The default packet data is
an incrementing value per byte. With this option the packet data alternate between 64 1’s
and 0’s that are aligned on a 64-bit PCI bus for maximum transitions.
-dids
display chip information such as the PCI DID and VID
