I have various ASA model in the network and various engineer work to create different ACL . Object and Groups, this become over head of too many Objects and Object-group with Duplicate IP.<\/p>\n\n\n\n
So i have used below Python script to extract the information from config.<\/p>\n\n\n\n
show run (download the ASA config on Linux host and run below Python file) <\/p>\n\n\n\n
