Administrator Guide

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.
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.
interactive Enter the keyword interactive to run offline diagnostics in interactive mode.
NOTE: On a C1048P, interactive diagnostic tests are supported only in
standalone mode; they are not supported in stacking mode and only from the
PE console.
testname name Enter the testname name parameters to run a specified offline diagnostic test. Enclose
the test-case name in double quotes (“ “). For example: diag level1 testname
“eepromTest”.
terminate Enter the keyword terminate to stop the offline diagnostic tests that are running.
Defaults All offline diagnostic tests are run on all switch CPUs (Control Processor, Route Processor, and line cards).
Command Modes EXEC Privilege
Usage Information
Before you use this command to run diagnostic test, make sure that the switch is offline (offline system
command).
You are prompted to reboot when the offline diagnostics complete.
The PE unit goes offline and reboots automatically after the test is completed.
Use the show diag command to view a summary of diagnostic information presented for each switch CPU. For
PE, this command is used to upload the TestReport from the PE to the C9000 in the
DEFAULT_DIAG_REPORT_DIR. For example:
Dell#pwd flash:/DEFAult_diag_report_dir
Use the show diag command to upload the diag TestReport as shown below:
Dell#show diag pe 8 stack-unit 0
% Diag Report file flash:/DEFAULT_DIAG_REPORT_DIR/TestReport-SU-0-
PE-8-20150328_200647.txt copied successfully.

At the end of offline diagnostic tests, a test report is generated. The filename of the report is TestReport-
{CP/LP/RP}-N.txt, where {CP/LP/RP}-N identifies the CPU and CPU ID on which the diagnostics were run:
Route Processor 0, Control Processor 0, and a line-card CPU {0–2}. The report is stored at flash:// and ramdisk:/
diagnostic. Offline diag test reports for port extender (PE) are stored in the following directory: flash:/
default_diag_report_dir. To view the test report, use the show file flash://filename
command. A sample filename is TestReport-LP-2.
