Enhancements to inline flow monitoring

You can now configure Junos OS to set the flow record value to 0 (zero) for rejected, discarded, and policed flows.You can configure the report-zero-oif-gw-on-discard statement at the [edit chassis fpc slot-number inline-services] hierarchy level to enable the FPC to set the value to 0 (zero) for the elements ipNextHopIPv6Address (Element ID 62), egressInterface (Element ID 14), and ipNextHopIPv4Address (Element ID 15) for the flow records for rejected, discarded, and policed flows. If the report-zero-oif-gw-on-discard statement is not configured , the flow records display the available information for these elements, which is the default behavior. After you configure the report-zero-oif-gw-on-discard statement, each sampled packet updates the forwarding action of that flow in the flow record. That is, the last sampled packet of the flow just before export determines the forwarding action of that flow. For example, in the case of a rate-limiting policer, forwarding action taken on a flow is not deterministic. The flow can be treated either as forwarded or as policed based on the forwarding action of the last sampled packet of that flow.
