Syntax Description
Defaults The default is disabled.
Command Types Switch command.
Command Modes Privileged.
Usage Guidelines The core dump feature generates a report of images when your system fails due to a software error. The core
image is stored in the file system. From this file, you can examine an error condition of a process when it is
terminated due to an exception.
The size of the file system depends on the memory card size. The core dump file generated is
proportional to the size of the system DRAM. Make sure that you have enough memory available to store
the core dump file.
In order to maintain the core dump image, the yield CPU is disabled during the c ore dump process. You
should have a redundant supervisor engine installed to take over normal operations. If the switch has a
redundant supervisor engine setup, the redundant supervisor en gine takes over automatically before the
core dump occurs. The previously active supervisor engine resets itself after the core dump completes.
