This read-write object selects which per-attack-type DoS frame counter to reset, using the same attack-type enumeration (land-attack, smurf-attack, ping-death-attack, all, and so on) as swDoSCtrlType. Admins write to it after reviewing DoS statistics to zero out the counters, either for one specific attack signature or for all(8) types at once, so future counts reflect only new activity. For example, writing all(8) clears every DoS-prevention frame counter on the switch, while writing smurf-attack(3) clears only the counter tracking detected Smurf-attack packets.
