docsDevFilterIpStatus 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 which 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.
docsDevFilterIpControl If set to discard(1), all packets matching this filter will be
discarded and scanning of the remainder of the filter list will be
aborted. If set to accept(2), all packets matching this filter will be
accepted for further processing (e.g., bridging). If
docsDevFilterIpContinue is set to true, see if there are other
matches, otherwise done. If set to policy (3), execute the policy
entries matched by docsDevIpFilterPolicyId in
docsDevIpFilterPolicyTable.
If is docsDevFilterIpContinue is set to true, continue scanning the
table for other matches, otherwise done.
docsDevFilterIpIfIndex The entry interface to which this filter applies. The value
corresponds to ifIndex for either a CATV MAC or another
network interface. If the value is zero, the filter applies to all
interfaces. Default value in cable modems is the index of the
customer-side (e.g. ethernet) interface. In CMTSs, this object
MUST be specified to create a row in this table.
docsDevFilterIpDirection Determines whether the filter is applied to inbound(1)
traffic—default, outbound(2) traffic, or traffic in both(3)
directions.
docsDevFilterIpBroadcast If set to true(1), the filter only applies to multicast and broadcast
traffic. If set to false(2), the filter applies to all traffic. Default:
false.
docsDevFilterIpSaddr The source IP address, or portion thereof, that is to be matched for
this filter. The source address is first masked (and'ed) against
docsDevFilterIpSmask before being compared to this value. A
value of 0 for this object and 0 for the mask matches all IP
addresses.
docsDevFilterIpSmask A bit mask that is to be applied to the source address prior to
matching. This mask is not necessarily the same as a subnet mask,
but 1's bits must be left-most and contiguous.
docsDevFilterIpDaddr The destination IP address, or portion thereof, that is to be
matched for this filter. The destination address is first masked
(and'ed) against docsDevFilterIpDmask before being compared
to this value. A value of 0 for this object and 0 for the mask
matches all IP addresses.
