Deployment Guide

A warning is displayed with a CLI prompt asking you to click Yes or No.
Dell#diag pe 0 stack-unit 0 level0 ?
Warning - PE-Unit 0 at PEID 0 will go offline to run the diagnostics.
Offline of system will bring down all the protocols and the system
will be operationally down, except for running Diagnostics.
PE unit will be automatically reloaded once the diagnostics tests are
completed.
Warning - The diagnostic execution will cause multiple link flaps on
the peer side
- advisable to shut directly connected ports
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 file into the PE master flash.
2. Upload the diagnostics report file 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 flash. The name of the file 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
show file file-name
The file-name refers to the file name that is displayed in the show diag pe command.
In this case, TestReport-SU-0-PE-0-20150312_045748.txt
show file flash://DEFAULT_DIAG_REPORT_DIR/TestReport-SU-0-PE-0-20150312_045748.txt
Diagnostic results are stored to a file in the flash using the filename format:
flash://DEFAULT_DIAG_REPORT_DIR/TestReport-SU-<stack-unit>-PE-<PEID>.txt
Dell#00:20:26 : Diagnostic test results are stored on flash://DEFAULT_DIAG_REPORT_DIR/
TestReport-SU-0-PE-020150312_045748.txt
The following example shows how to verify the offline/online status of the PE.
Dell#diag pe 255 stack-unit 2 alllevels
Warning - PE-Unit 2 at PEID 255 will go offline to run the diagnostics.
Taking Port Extender unit offline for running diagnostics
will make it operationally down, causing traffic disruption through the unit.
If stacking is configured, the unit roles may change. This unit 2 will become standalone
once diags are executed.
PE unit will be automatically reloaded once the diagnostics tests are completed.
Warning - The diagnostic execution will cause multiple link flaps on the peer side -
advisable to shut directly connected ports
Proceed with PE diag [confirm yes/no]:yes
