This writable action object lets a management station clear the counters stored in this archived Ethernet port history bin. It gives the admin a way to purge a specific known-bad historical record, such as one captured during a port reset, rather than letting it skew later trend comparisons. For example, after confirming a history bin's error counts were caused by a brief maintenance-window flap, the admin would write to cmEthernetTrafficPortHistoryAction to clear that specific bin.
