Troubleshooting the Software Configuration
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.
h2-macallan1# request platform software process core fed active
Process : fed main event (28155) encountered fatal signal 6
Process : fed main event stack :
SUCCESS: Core file generated.
h2-macallan1#dir bootflash:core
Directory of bootflash:/core/

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 crashinfo: 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:
flash:
ftp:
http:
https:
null:
nvram:
rcp:
running-config Update (merge with) current system configuration
scp:
startup-config Copy to startup configuration
syslog:
system:
tftp:
tmpsys:
The general syntax for copying onto TFTP server is as follows:
Switch#copy crashinfo: tftp:
Source filename [system-report_1_20150909-092728-UTC.gz]?
-rw- 1 May 23 2017 06:05:17 +00:00
