Hi all,
On 6509 with dual sup 32 and 720 is crashinfo file is enabled by default on the running config
or
do we need to configure this option on switch.
How can we check in running config if crashinfo is configured or not ?
Thanks

Hi Mahesh,
To add to what's already been said, on a Cisco 3600 series only, there is a way to disable the creation of crashinfo files via the no exception crashinfo file device:filename command. Refer below for more information:
http://www.cisco.com/en/US/docs/ios/12_3/configfun/command/reference/cfr_1g03.html#wp1028469
You can configure the exception crashinfo maximum files command, however, on a Cisco IOS device to automatically delete old crashinfo files. This functionality helps the device create space to write the new crashinfo files when the device crashes. This feature also allows you to configure the number of most recent crashinfo files on a device to be saved when no file system has enough space in which to write new crashinfo files.
This feature was introduced in IOS version 12.3(11)T. This feature is useful when there isn't enough space available across the device's file systems to write new crashinfo files.
Please refer below for more information:

Hope it helps,

Hi Mahesh,
You don't need to enable it. When the system crashes, the crash file will be saved into your flash card.

Hi Mahesh,
Crashinfo is enabled by default on IOS.
There is no configuration to manually enable/disable it to my knowledge.

Hi Reza,
so as per posts no config is needed and crash file is enabled by default and info is saved to bootflash only if it has sufficient free memory right?
thanks for reply

exception crashinfo maximum files
This command is helpful. (+5)

Mahesh,
As per the previous reply, it is clear that the Crashinfo file is by default available and there is no need to configure.
Howver to answer you other question:
How can we check in running config if crashinfo is configured or not ?
Login to the 6509 Switch in Privelege Login
-config)# dir /all
You see all the available Directory in your Device
The Crashinfo file is generally stored in the SUPboot FLash or in DFC memory of the Line Card
You can copy to the TFTP server and use it
Refer the Cisco Link for more information
