| Description | For outgoing Service Flows, this attribute counts
the number of Packet Data PDUs forwarded to this Service
Flow. For incoming upstream CMTS service flows,
this attribute counts the number of Packet Data PDUs
actually received on the Service Flow identified by
the SID for which the packet was scheduled. CMs not classifying
downstream packets may report this attribute's
value as 0 for downstream Service Flows. This
attribute does not count MAC-specific management
messages.
Particularly for UGS flows, packets sent on the primary
Service Flow in violation of the UGS grant size should
be counted only by the instance of this attribute
that is associated with the primary service flow.
Unclassified upstream user data packets (i.e., non-
MAC-management) forwarded to the primary upstream
Service Flow should be counted by the instance of this
attribute that is associated with the primary service
flow.
This attribute does include packets counted by
ServiceFlowPolicedDelayPkts, but does not include packets
counted by ServiceFlowPolicedDropPkts and
ServiceFlowPHSUnknowns.
This counter's last discontinuity is the
ifCounterDiscontinuityTime for of the associated MAC Domain
interface index. |
