However, the server option supports only RP coredumps; it does not support CP coredumps. By default the kernel core dump is sent to the root directory of the internal flash CP and the CORE_DUMP_DIR directory for RP. Application core dump-On the E-Series, the application core dump has the file name format f10{cp|rp{1|2}}.acore.gz, where is a time stamp, and FTOS writes it to the internal flash. Note: The kernel core dump can be large and may take up to 5 to 30 minutes to upload. FTOS 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 core dump is aborted. On the S-Series, if the FTP server is not reachable, the application core dump is aborted. The FTOS High Availability module is aware of the core dump upload, and it does not reboot the crashed RPM until the core dump has completed or is aborted. Line card core dumps Line card core dumps preserve critical status information for cards which experience a task crash. Message 21 Task Crash Detection %E48TF:0 %TME-2-TASK SUSPENDED: LINECARD TASK SUSPENDED. SAVING FAILURE RECORD IN PROGRESS Writing a line card core dump to memory on the RPM requires 5 to 30 minutes. During this time, the physical interfaces remain in their current state, which is normally operationally up. This behavior assumes that most FTOS agent tasks running on the line card CPU continue to operate correctly and that you want to maximize uptime by having packets continue to flow while FTOS writes the core dump. If you want to failover to a redundant system when a line card exception occurs, use the command logging coredump linecard port-shutdown to shut down ports during a core dump so that the backup system can take over. Line card core dumps are disabled by default. To enable line card core dumps and specify the shutdown mode: Step Task 1 Enable line card core dumps and specify the shutdown mode. Command Syntax Command Mode logging coredump linecard {all | {0-13}} EXEC Privilege [port-shutdown | no-port-shutdown] Note: In the absence of port-shutdown and no-port-shutdown, the option no-port-shutdown is applied. 1100 | E-Series TeraScale Debugging and Diagnostics
