The following procedures are for checking switch-specific components.
Testing a port’s external transmit and receive path
1.
Connect to the switch and log in as admin.
2.
Connect the port you want to test to any other switch port with the cable you want to test.
3.
Enter the
portLoopbackTest -lb_mode 2
command.
Testing a switch’s internal components
1.
Connect to the switch and log in as admin.
2.
Connect the port you want to test to any other switch port with the cable you want to test.
3.
Enter the
portLoopbackTest -lb_mode 5
command where
5
is the operand that causes the test
to run on the internal switch components (this is a partial list—refer to the
Fabric OS Command
Reference
for additional command information):
[
-nframes
count
]—Specify the number of frames to send.
[
-lb_mode
mode
]—Select the loopback point for the test.
[
-spd_mode
mode
]—Select the speed mode for the test.
[
-ports
itemlist
]—Specify a list of user ports to test.
Testing components to and from the HBA
1.
Connect to the switch and log in as admin.
2.
Enter the
portTest
command (see the
Fabric OS Command Reference
for information on the
command options).
See
Table 7
on page 37 for a list of additional tests that can be used to determine the switch
components that are not functioning properly. See the
Fabric OS Command Reference
for
additional command information.
The HBA's
bcu fcDiag
--
linkbeacon
command can be used to beacon a target port on the switch.
For more information on using this command, refer to the
Brocade Adapters Administrator’s Guide
.
