This object reports the configured aggregate-throughput threshold above which the device fires the ciscoRasTooHighThroughput trap, and per the desc that notification stays suppressed until throughput actually drops back below this value, preventing repeated alert storms while the device remains overloaded. An admin sizing WAN capacity for the VPN concentrator sets this to a value just under the link's real ceiling so they get one clear warning as utilization approaches saturation rather than being flooded with retriggering alerts. Setting this to 900,000,000 octets/sec on a device with a 1 Gbps uplink gives an early warning before the link actually saturates.
