ip directed broadcast prevents directed broadcasts from being routed, not from local directed broadcasts.  The only way to prevent the switch from being able to ping the local broadcast net is with an ACL on the switch configured on egress to the management VLAN (in the case of a workgroup switch), or configured on egress to the VLAN in question (if the switch has a layer-three VLAN configured for the VLAN in question).
