This value sets the upper limit of incoming broadcast traffic on a port, measured over a 1-second interval in the unit chosen by hh3cStormCtrlBroadcastUnit, above which the port is put into controlled status and stops forwarding. An admin tunes this to protect the port from broadcast storms while still allowing normal ARP or DHCP broadcast bursts through. For example, with the unit set to packetsPerSecond, a value of 3000 caps broadcast traffic at 3000 packets per second before the port is throttled.
