Configuration files on a switch

[Pradeeban.B]

What are the other old configuration files remain in memory, after erasing start-up config file? 

How can I find them by code?

all the configuration stored in NVRAM,  you can also keep the backup in a flash if you like to.

Once you do write erase and reboot, the switch go to default mode.

but if you like to delete the VLAN database some switches you can delete vlan.dat file.

Thank you for your response.

I expected command code which lists other config files from the memory.

But you have also cleared other theoretical doubt about flash.

Thank you.

You can use other command suggested

dir all-filesystems

[Seb Rupik]

The command you are looking for is dir all-filesystems

Normally you cannot, as the device only keeps one copy.

PS:

Oh, if you have in mind, something like a PC "undelete" utility, you might, or might not, be able to find prior image(s) daa in flash, but you'll also face some of the same issues you would for a PC "undelete" utility.
