It is not common see a Cisco crash: Software forced crash, Bus Error, Software watchdog timeout, and so on But if you would do it, there is a pretty trick : its the test crash command, an hidden IOS command. This can help you if you are lucky enough to have the real crash exactly like one of those you can test with test crash command.

Below, the test crash menu: C i s c o z i ne # t e s t c r a s h W A R N I N G : C o m m a nd s e l e c t i on s m a r k e d w i t h ' ( c r a s h r ou t e r ) ' w i l l c r a s h r ou t e r w he n i s s ue d .

To generate a Cisco crash, type C to enable Cisco crash feature. Then select the crash type that you would generate. How Cisco test crash command works? In this example, I have selected the s option to save crashinfo to the flash. The file will be named like: crashinfo_YYYYMMDD- hhmmss, where: YYYY is the year, like 2009 MM is the month, like 06 DD is the day, like 18 hh are the hours, like 15 mm are the minutes, like 03 ss are the seconds, like 34 As you can see, the file saved on the flash memory (due a Software forced crash, option #6) could be read with the command more. Remember that it is not easy understand the crashinfo file
