A statistic displaying the number of valid ingress packets received on a SAP, or subscribers on that SAP, is shown in the sap-stats output. This is available for SAPs in all services. This is particularly useful to display SAP level traffic statistics when forwarding classes in a SAP ingress policy have been redirected to an ingress queue group.
In the following example, traffic is received on an ingress FP policer with a packet-byte-offset of subtract 10. It can be seen that the ingress queueing stats and offered forwarding engine stats are all zero as the traffic is using the FP ingress policer. The Received Valid statistic is non-zero and matches that seen on the ingress FP queue group, with the difference being that the packet-byte-offset is applied to the queue group policer octets but not the Received Valid octets.
The value in the Received Valid field may not instantaneously match the sum of the offered stats (even in the case where all traffic is using the SAP queues) when traffic is being forwarded; however, when the traffic has stopped, the Received Valid equals the sum of the offered stats.
