Hi @Samanth Krishna Dhas​ - The 2000 rule limit is for each security check which has learning enabled.

You can find more information here - https://docs.netscaler.com/en-us/citrix-adc/current-release/application-firewall/profiles/learning.html.

What you're looking at is the is the learn msgs/second rate limit. Msgs over this limit will be dropped.
