Enabling and Copying Core Dumps Chapter 1 Managing the CSS Software Enabling and Copying Core Dumps A core dump occurs when the CSS experiences a fatal error. The CSS allows you to enable or disable core dumps. Core dumps are enabled by default. When the CSS experiences a fatal error and core dumps are enabled, the CSS: • Writes information about the fatal error to the Core directory of the volume root (for example, c:\core) on either the hard or Flash disk. The CSS stores one dump file per slot for each card type until the disk (Flash or hard disk) is full. Files can be 10 to 20 MB in size. • Reboots automatically. Note Core dump information is for Cisco Technical Assistance Center (TAC) use only. When the CSS experiences a fatal error and core dumps are disabled, the CSS reboots automatically. The CSS does not write information to the hard disk or the Flash disk. For a Flash disk-based system, if the core dump file is older than 15 minutes, the file may be overwritten. If you want to save the core dump file for later examination, archive the file to another directory or disk before it is overwritten. For details on using the archive log command, see the "Archiving the Startup-Config File" section.
