Fabric OS 5.2.x administrator guide 295
Identifying media-related issues
This section provides procedures that help pinpoint any media-related issues in the fabric. The tests listed in
Table 60
are a combination of
structural
and
functional
tests that can be used to provide an overview of
the hardware components and help identify media-related issues.
•
Structural
tests perform basic testing of the switch circuit. If a structural test fails, replace the main board
or port blade.
•
Functional
tests verify the intended operational behavior of the switch by virtue of running frames
through ports or bypass circuitry.
The following procedures are for checking switch-specific components.
To test 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
crossPortTest
command with the following operands (this is a partial list. Refer to the
Fabric OS Command Reference Manual
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.

[-lb_mode

]
[-gbic_mode

Functional test of port external
transmit and receive path.
The
crossport
is set to loopback
using an external cable by default.
However, this command can be used
to check internal components by
setting the
lb
operand to 5.
fporttest
[-nframes
count
] [-ports

]
[-seed
payload_pattern
]
[-width
pattern_width
] [-size
pattern_size
]
Tests component to/from and HBA.
Used to test online F_Port devices,
N_Port devices, SFPs, and GBICs.
loopporttest
[-nframes
count
]
[-ports
itemlist
][-seed
payload_pattern
]
[-width
pattern_width
]
Only tests components attached to a
switch that are on a FC-AL.
spinfab
[ -nmegs count ] [ -ports
itemlist ] [ -setfail mode ]
Tests switch-to-switch ISL cabling and
trunk group operations.
