Using the crashinfo Files
The crashinfo files save information that helps Cisco technical support representatives to debug
problems that caused the Cisco IOS image to fail (crash). The switch writes the crash information to the
console at the time of the failure. The switch creates two types of crashinfo files:
•
•
Basic crashinfo Files
The information in the basic file includes the Cisco IOS image name and version that failed, a list of the
processor registers, and a trace. You can provide this information to the Cisco technical support
representative by using the show tech-support privileged EXEC command.
Basic crashinfo files are kept in this directory on the flash file system:
flash:/crashinfo/.
The filenames are crashinfo_n where n is a sequence number.
Each new crashinfo file that is created uses a sequence number that is larger than any previously existing
sequence number, so the file with the largest sequence number describes the most recent failure. Version
numbers are used instead of a timestamp because the switches do not include a real-time clock. You
cannot change the name of the file that the system will use when it creates the file. However, after the
file is created, you can use the rename privileged EXEC command to rename it, but the contents of the
renamed file will not be displayed by the show tech-support privileged EXEC command. You can
delete crashinfo files by using the delete privileged EXEC command.
You can display the most recent basic crashinfo file (that is, the file with the highest sequence number
at the end of its filename) by entering the show tech-support privileged EXEC command. You also can
access the file by using any command that can copy or display files, such as the more or the copy
privileged EXEC command.
Extended crashinfo Files
The switch creates the extended crashinfo file when the system is failing. The information in the
extended file includes additional information that can help determine the cause of the switch failure. You
provide this information to the Cisco technical support representative by manually accessing the file and
using the more or the copy privileged EXEC command.
