Hello All,
i have a network setup operational, have one Cisco Core Switch (4506-E) with SUP 7 engine (WS-X45-SUP7-E). Three modules are 48 Port 1G SFP Ports (WS-X4448-GB-SFP).
Have 130+ access switches (cisco 2960). All the access switches are connected to the Core Switch mentioned above using 1G fiber ports.
CPU utilization has been going high and whenever it goes high, reason is "ARP Input" usually at the peak time, if i do "show process cpu detailed ", it shows "ARP Input" under "iosd" which has a higher percentage.
On access switches i have configured storm contro broadcast configuration on interfaces but it has not been effective in putting those interfaces in an err-disabled state who send too many broadcast packets.
int range fastEthernet 0/1 - 48

ip dhcp snooping limit rate 70
storm-control broadcast level 30.00 10.00

i want to change the value of broadcast levels and use pps value instead of %age, but not sure of how to get a correct number of setting these levels
need help in modifying the storm control configuration.
