Controls and reflects the status of rows in this table. Specifying only this object (with the appropriate index) on a CM is sufficient to create a filter row that matches all inbound packets on the ethernet interface and results in the packets being discarded. docsDevFilterIpIfIndex (at least) must be specified on a CMTS to create a row. Creation of the rows may be done via either create-and-wait or create-and-go, but the filter is not applied until this object is set to (or changes to) active. There is no restriction in changing any object in a row while this object is set to active.
