Measuring syn packets

[wanab]

Hi,

To apply rate-limit to the interface it is recommended to first measure the amount of syn packets during normal state.

Can the router indicate the amount of syn packets passing through it and how to do it?

Thanks in advance.

This document should help you setup a “logged-input” access-list that will get you syn counts:
