Description: This attribute counts the number of segments which the CMTS segment reassembly function determines were lost. This attribute only gathers information for Segment Header On service flows. Discontinuities in the value of this counter can occur at reinitialization of the managed system, and at other times as indicated by the value of ifCounterDiscontinuityTime of the associated MAC Domain interface index.
What is docsQosServiceFlowCcfStatsSgmtLost?
This counter tracks the number of payload segments determined to be lost by the CMTS's segment reassembly function on service flows with Segment Header enabled. Cable network operators monitor this metric to identify data link quality issues and cable modem problems that cause packets to be dropped during transmission. Increasing segment loss indicates congestion, interference, or modem errors that require network capacity upgrades or customer support intervention.
