An entry in cMTInterfaceMetricStatsTable represents interface information of a hop on the path associated to a Mediatrace session such as ingress interface speed, egress interface speed, etc. The devices creates a row in the cMTInterfaceMetricStatsTable when a Mediatrace session starts collecting an interface metrics data and has been configured to compute interface metrics. Likewise, the device destroys a row in the cMTInterfaceMetricStatsTable when the corresponding Mediatrace session has ceased collecting the interface metrics data (e.g., when a scheduled session has timed out). A single row corresponds to a interface information of a hop on the path discovered for a session and is uniquely identified by cMTSessionNumber, cMTSessionLifeNumber, cMTBucketNumber, cMTHopStatsAddrType and cMTHopStatsAddr. The created rows are destroyed when the device undergoes a restart.
