the line-card processor (LP) and 0 for the Control processor (CP) and Route Processor (RP). To display
the system results in this text file, use the

Important Points to Remember
• Offline diagnostics can only be run when the unit is offline.
• You can only run offline diagnostics on a unit to which you are connected via the console. In other
words, you cannot run diagnostics on a unit to which you are connected to via a stacking link.
• Diagnostic results are printed to the screen. The Dell Networking OS does not write them to memory.
• Diagnostics only test connectivity, not the entire data path.
diag
Run offline diagnostics on all CPUs or on a specified CPU in the switch.
Syntax
diag {all | {{cp | rp | linecard}
unit-id
} [alllevels | level0
| level1 | level2] [interactive] [testname
name
] [terminate]
Parameters
all
Enter the keyword
all
to run offline diagnostic tests on all
Z9500 CPUs, including the Control Processor, Route
Processor, and line cards.
cp
unit-id
Enter the
cp
unit-id
parameters to run offline diagnostic
tests only on the Control Processor CPU. The Control
Processor CPU ID is 0.
rp
unit-id
Enter the keyword
rp
unit-id
parameters to run offline
diagnostic tests only on the Route Processor CPU. The Route
Processor CPU ID is 0.
linecard
unit-id
Enter the
linecard
unit-id
parameters to run offline
diagnostic tests only on a specified line card. The range of
line-card CPU IDs is from 0 to 2. Each line-card CPU
processes packets on the corresponding Z9500 line card; for
example, line-card CPU 1 processes packets on line card 1.
alllevels
Enter the keyword
alllevels
to run the complete set of
offline diagnostic tests.
level0
Enter the keyword
level0
to run Level 0 diagnostics. Level
0 diagnostics check for the presence of various components
and perform essential path verifications. In addition, they
verify the identification registers of the components on the
board.
level1
Enter the keyword
Level1
to run Level 1 diagnostics. Level 1
diagnostics is a smaller set of diagnostic tests with support
for automatic partitioning. They perform status/self test for
all the components on the board and test their registers for
appropriate values. In addition, they perform extensive tests
on memory devices (for example, SDRAM, flash, NVRAM,
EEPROM, and CPLD) wherever possible. There are no tests
on 10G links. At this level, ports are shut down automatically.
