file, you must perform an FTP to the Control Processor CPU flash directory where the application core dump is stored in the following formats: • An application core dump generated from CP of the RPM: f10Ch_rpm_cp__.acore.gz • An application core dump from RP application: f10Ch_rpm_rp__.acore.gz • An application core dump from LP application: f10Ch_lp__.acore.gz • An application core dump generated from LM: f10Ch_lp__.acore.gz Where cpu specifies a system's CPU and is one of the following values: cp (Control Processor), rp (Route Processor), lp0 (line-card processor 0), lp1 (line-card processor 1), or lp2 (line-card processor 2); application specifies the name of the executable that has crashed; timestamp is a text string in the format: yymmddhhmmss (YearMonthDayHourMinuteSecond). You can also configure the system to automatically move (upload) an application core dump to an external FTP server. Use the logging coredump server server-ip-address username ftpusername password ftp-password command in global configuration mode to configure an FTP server. When you enter the logging coredump server command, you are required to enter a password. Use the password of the FTP server where the core files are to be copied. The password can be up to 15 characters; special characters are allowed. After you enter the password, an FTP URL is created with the credentials in the operating system. The CLI monitors application core dumps in the unit. NOTE: On the system, when you enable core dumps of application crashes to be uploaded to an FTP server, only core dumps from the Control Processor are uploaded to the server. Application core-dump files from the Route Processor and line-card CPUs are moved to flash memory on the Control Processor CPU and can be accessed by performing an FTP to the Control Processor (CP) core-dump directory: • The application core-dump file for the Route Processor is stored at: flash:/CORE_DUMP_DIR/ f10rp_application_timestamp.acore.gz • The application core-dump file for a line-card processor is stored at:flash:/CORE_DUMP_DIR/ f10lpslot-number_application_timestamp.acore.gz To disable the automatic uploading of application core dumps, enter the no logging coredump server command. Mini Core Dumps Dell Networking OS supports mini core dumps for kernel crashes. The mini core dump applies to Master units. Kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other very minimal information that can be used to debug a crash. These files are small files and are written into flash until space is exhausted. When the flash is full, the write process is stopped. Debugging and Diagnostics 365
