Over the past few weeks I have taken a number of support calls from customers who were looking for some assistance with their Cisco ASA NetFlow configuration using ASDM. So I figured that I would take this opportunity to write a blog walking through the configuration steps to supplement the existing blogs that show a video or have a series of images.
In my opinion, the easiest way to get NSEL exporting from these security appliances is through the use of the ASDM interface. This simple, GUI-based firewall management tool allows you to quickly configure the Cisco ASA without having to use the cumbersome command-line interface. Although I must admit that configuring the Cisco ASA using the CLI is really not that much different that configuring NetFlow on any other router or switch.

Most network professionals are interested in seeing what applications are in their environment and who is using them. In the spirit of catching them all, I set out to find Pokemon GO network traffic with NetFlow.
