To confirm the size of your running configuration file, follow this procedure:
Procedure
Step 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 page, select the device you want to connect to, and click >_ Command Line Interface button in the Device Actions pane.
|
Step 2 | At the prompt type copy running-config flash |
Step 3 | When prompted for the Source filename, don't type anything and press <Enter> |
Step 4 | 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. |
Step 5 | At the prompt, type show flash |
Step 6 | 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
