stack-unit unit-
number
Enter the stack-unit value to run offline diagnostic test on a specified stack-
unit. The stack-unit range is 0 to 7.
alllevels Enter the keyword all levels 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.
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-
