Description: The purpose of this table is to provide an agent the ability to easily determine which rules have been used on a given bridge port. A row will only be present when the rule which the instancing describes has been used. The agent may remove a row (and clear the used status) by setting the etsysPolicyRulePortHit leaf to False. PolicyClassificationRuleType together with a length, matching data and a relevant bits field, port type, and port number (port number zero is reserved to mean any port), scoped by a etsysPolicyRuleProfileIndex, and preceded by a dot1dBasePort is used as the table index.
