Using the crashinfo Files
Extended crashinfo files are kept in this directory on the flash file system:
flash:/crashinfo_ext/.
The filenames are crashinfo_ext_n where n is a sequence number.
You can configure the switch to not create the extended creashinfo file by using the no exception
crashinfo global configuration command.
