I am getting some broadcast problems at some sites with L2 and L3 switches.Actually at each site both L2 and L3 switches are connected with non-manageable switches or hubs , so i m getting to much broadcast packets on those interfaces. I have tried to stop this with storm-control feature and then with ACLs. In ACL i have denied 255.255.255.255 and even broadcast IP of those subnets but still the broadcast packets are coming with same pace. I have also tried flow control but no gain in it. Plz help me to sort out this issue.
