downstream-rate (Traffic Shaping)


Hierarchy Level


Specify a recommended shaping rate to be applied to downstream traffic on an interface.

For ANCP interfaces, this configured rate is used as the default value for the Juniper VSA Downstream-Calculated-Qos-Rate (26–141) when the router has not received and processed the attributes from the access node.

For L2TP, the rate is configured on an underlying PPPoE logical interface for a subscriber on an MX Series router acting as a LAC. When the subscriber is tunneled, this rate, referred to as speed for L2TP, is sent to the LNS in the ICCN message as AVP 24.


rate—Traffic rate in bits per second.

  • Range: 1000 through 4,294,967,295 bits per second
