This read-write integer (0-11560000 bps) sets the peak downstream rate for a service type, with policing handled by the appropriate Ethernet card, and setting it to 0 stops downstream traffic entirely for that service type. An admin uses this both to cap a tier's throughput and, in the extreme, to suspend downstream service. For example, an admin temporarily sets hcxDnStrmRate to 0 for a delinquent account's service type to suspend its downstream traffic without deleting the configuration.
