Description
8.3.7.0
Introduced on the S4810.
Usage Information
The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. Dell Networking OS does not
overwrite application core dumps so you should delete them as necessary to conserve space on the flash; if the
flash is out of memory, the coredump is aborted. Dell Networking OS completes the coredump process and wait
until the upload is complete before rebooting the system.
Offline Diagnostic Commands
The offline diagnostics test suite is useful for isolating faults and debugging hardware. While tests are running, Dell Networking OS results
are saved as a text file (TestReport-SU-X.txt) in the flash directory. This
show file
command is available only on master and standby.
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.
•
Diagnostics only test connectivity, not the entire data path.
diag stack-unit
Run offline diagnostics on a stack unit.
Syntax
diag stack-unit
number
[alllevels | level0 | level1 | level2 | interactive
test-id
] verbose [no-reboot]
Parameters
number
Enter the stack-unit id.
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.
level2
Enter the keyword
level2
to run Level 2 diagnostics. Level 2 diagnostics are a full set of
diagnostic tests with no support for automatic partitioning. Level 2 diagnostics are used
primarily for on-board loopback tests and more extensive component diagnostics. Various
components on the board are put into Loopback mode and test packets are transmitted
through those components. These diagnostics also perform snake tests using VLAN
configurations.
