Version 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. On the S-Series, if the FTP server is not
reachable, the application 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.
• Diagnostic results are printed to the screen. Dell Networking OS does not write them to memory.
• Diagnostics only test connectivity, not the entire data path.
