Confirming ASA Running Configuration Size

To confirm the size of your running configuration file, follow this procedure:

  1. Access the ASA's command line interface in one of these ways: 
  • Open a terminal window and log into your ASA using SSH. Elevate your privilege to "privileged EXEC" mode so you see the prompt with hostname#.
  • If you managed to get your ASA onboarded, open the Devices & Service page, select the device you want to connect to, and click >_ Command Line Interface button in the Device Actions pane. See Using the Command Line Interface for more detailed information. 
  1. At the prompt type copy running-config flash
  2. When prompted for the Source filename, don't type anything and press <Enter>
  3. When prompted for the destination filename, enter a name for the output file. After ASA copies the running configuration the file you specified, it returns you to the privileged EXEC prompt.
  4. At the prompt, type show flash
  5. Look in the length column. If your file is over 4718592 bytes, it is larger than 4.5 MB.

Here is a sample set of commands and output:

asa1# copy running-config flash

Source filename [running-config]? 

Destination filename [running-config]? running-config-output

Cryptochecksum: 725f4c1c 4adfb8a9 8b3e7a6d 49e3420d
