We would like to configure broadcast storm control in our LAN to detect/avoid mac-address flooding. What is the best way and Can I know how to decide the raising threshold & falling threshold values ?.. Please suggest.
the best way is to monitor your network fir 5-6 days in order to find out the normal pattern of broadcast traffic. Then based on results form this monitoring process you can set the thresholds of broadcast traffic.
Try to find a program in order to monitor your network. You can try a free version of netflow in order to check the normal traffic pattern of your network.
