Core dumps contains a copy of the router's entire memory contents. In some circumstances this will help technical support to determine what is causing the crash of your network device or will help the developers to pin-point bugs.
Cisco provides a simple way for doing this. In our case we are going to configure and FTP server as the destination for the core dumps.
By default, the processor memory core dump is written to a file named "hostname-core", or "hostname-coreiomem" on certain platforms with IO Memory.
Lets assume our FTP server is 150.100.1.100, and that we have a username and password of "cisco" to access the server. The configuration will look like:
You can test your configuration by generating a dump without rebooting the device. From enable mode execute "write core" and this will write a dump to your FTP.
