Saving Cisco running configuration

I just want to make sure I understand this correctly. I have a Cisco ASA 5505 which I have configured the way I want it using the ASDM web interface. My understanding is that all the changes I have made are only in the running configuration at this point and would not persist through a reboot. I believe what I need to do to make them stick is save them to flash. Is this correct?

Hi this may help you.
copy running-config startup-config

You are correct

when you turn on an ASA this is what happens

The Low Level ROMMON operating system loads and looks for a bootable Operating system in flash memory
The Operating system loads.
The OS Copies the Startup configuration into RAM (that's just normal RAM chips like your PC has) this becomes the running config.

You can change the running config all you want but if you done save it (copy to flash) then on next reboot the start-up config will load again.

That's why the poster above said
 copy running-config startup-config

Because that's what happens, though if you wok at command line for any length of time use "wr mem" instead (its less typing.)

On ikalmar's second screen shot above you will see the same thing done from ASDM (save running configuration to flash).
