5. Bootup logs 6. Reload logs 7. Certain types of /proc information This information is stored in separate files which are then archived and compressed into one bundle. This makes it convenient to get a crash snapshot in one place, and can be then moved off the box for analysis. This report is generated before the switch goes down to rommon/bootloader. Except for the full core and tracelogs, everything else is a text file. Use the request platform software process core fed switch active command to generate the core dump. Device# request platform software process core fed switch active SUCCESS: Core file generated.

Ifit cannot be saved to the crashinfo partition for lack of space, then it will be saved to the /flash directory. To display the files, enter the dir crashinfo: command. The following is sample output of a crashinfo directory: Device# dir crashinfo:

The name of the most recently generated system report file is stored in the last_systemreport file under the crashinfo directory. The system report and crashinfo files assist TAC while troubleshooting the issue.
The system report generated can be further copied using TFTP, HTTP and few other options.
