Enabling Core Dump File Generation
You can enable the device to automatically generate a core dump file upon a device crash. The core dump is a copy of the device's memory image at the time of the crash. The device generates a new core dump file each time it crashes, replacing the previous core dump file (if exists). The core dump file provides you with a powerful tool for determining the cause of the crash.
You can also configure the device to send the core dump file to a TFTP server (defined by IP address). If you don't configure an address, the core dump file is saved on the device's flash memory (if it has sufficient memory). The core dump file is saved as a binary file, using the following file name format: core_<Device Name>_ver_<Firmware Version>_mac_<MAC Address>_<Date>_<Time>. For example: "core_acDevice_ver_720-8-4_mac_00908F099096_1-02-2015_3-29-29".
