The size of the file system depends on the size of your memory card. An error process will generate a
core image that is proportional to the size of the system DRAM. Make sure that you have enough
available memory to store the core dump file.
Specifying the Core Image Filename
Enter the
set system core-file
command to specify the core image filename. The default filename is
“slot0:crash.hz.” This command automatically checks the validity of the device name that you input.
To specify the core image filename, perform this task in privileged mode:
This example shows how to specify the core image filename:
Console> (enable)
set system core-file slot0:core.hz
System core-file set.
Console> (enable)
Displaying the Stack Dump
A stack dump provides only the images that are related to a particular process that has caused the system
to fail. This image stack is displayed on the console and is also saved in the log area. The stack dump is
automatic and becomes available when you enter the
show log
command after you reboot your system.
To display the log information, perform this task in normal mode:
