Except for the full core and tracelogs, everything else is a text file.
Use the request platform software process core fed active command to generate the core dump.

Crashinfo Files
By default the system report file will be generated and saved into the /crashinfo directory. Ifit cannot be saved
to the crashinfo partition for lack of space, then it will be saved to the /flash directory.
To display the files, enter the dir crashinf o:command. The following is sample output of a crashinfo directory:
Switch#dir crashinfo:
Directory of crashinfo:/
23665 drwx 86016 Jun 9 2017 07:47:51 -07:00 tracelogs
11 -rw- 0 May 26 2017 15:32:44 -07:00 koops.dat
12 -rw- 4782675 May 29 2017 15:47:16 -07:00 system-report_1_20170529-154715-PDT.tar.gz
1651507200 bytes total (1519386624 bytes free)
System reports are located in the crashinfo directory in the following format:
system-report_[switch number]_[date]-[timestamp]-UTC.gz
After a switch crashes, check for a system report file. The name of the most recently generated system report
file is stored in the last_systemreport file under the crashinfo directory. The system report and crashinfo files
assist TAC while troubleshooting the issue.
The system report generated can be further copied using TFTP, HTTP and few other options.
Switch#copy crashinfo: ?
crashinfo: Copy to crashinfo: file system
flash: Copy to flash: file system
ftp: Copy to ftp: file system
http: Copy to http: file system
https: Copy to https: file system
null: Copy to null: file system
nvram: Copy to nvram: file system
rcp: Copy to rcp: file system
running-config Update (merge with) current system configuration
scp: Copy to scp: file system
startup-config Copy to startup configuration
syslog: Copy to syslog: file system
system: Copy to system: file system
tftp: Copy to tftp: file system
tmpsys: Copy to tmpsys: file system
The general syntax for copying onto TFTP server is as follows:
Switch#copy crashinfo: tftp:
Source filename [system-report_1_20150909-092728-UTC.gz]?
