Abstract
A router stores core file into a local flash memory after detecting a shutdown event. In order to increase the amount of core file data that can be stored, the core file is first compressed before being downloaded into the local flash memory. Because the flash memory is local, the network device is not required to dump the core file over an external network to an external network server. Thus, network interface elements in the network device do not have to be functional in order for the core dump to be successful. During the shutdown routine, interrupts are disabled for all processing elements that are not needed to perform the core download. The core dump is therefore faster and more reliable and allows more effective system debugging than present core download procedures.
