Proceed with PE diag [confirm yes/no]:yes
After completing the diagnostics on the PE, the PE reboots automatically reboots and then the switch and PE connection is
established. The switch copies the diagnostic report le into the PE master ash.
2 Upload the diagnostics report le into the switch.
EXEC Privilege mode
show diag pe pe-id stack-unit unit-number
This command copies the diagnostics report from the PE to the switch’s ash. The name of the le that is copied is printed as part of
the CLI output.
For example:
Dell#show diag pe 0 stack-unit 0
% Diag Report fileflash:/DEFAULT_DIAG_REPORT_DIR/TestReport-SU-0-PE-0-20150312_045748.txt
copied successfully.
3 View the results of the diagnostics test from the console.
EXEC Privilege Mode
