Setting a Recommended Shaping Rate for Traffic on ANCP Interfaces
When the access node sends information about the downstream and upstream calculated traffic rates for an interface, those values are used to shape the traffic sent to the interface so that it matches the subscriber local loop speed. You can specify recommended values to be used when the router does not receive this information from the access node. In this event, these recommended values are used as the default values for two Juniper VSAs, Downstream-Calculated-Qos-Rate (IANA 4871, 26–141) and Upstream-Calculated-Qos-Rate (IANA 4874, 26-142).
The Downstream-Calculated-Qos-Rate VSA conveys the transmit speed, which is the recommended traffic value in bits per second used for downstream traffic for an ANCP interface. The Upstream-Calculated-Qos-Rate VSA conveys the receive speed, which is the recommended traffic value in bits per second used for upstream traffic for an ANCP interface.
To configure recommended traffic shaping values for an interface:
- Set the rate in bits per second for downstream traffic
for the interface.[edit protocols ancp interface interface-name advisory-options]user@host# set downstream-rate rate
- Set the rate in bits per second for upstream traffic for
the interface.[edit protocols ancp interface interface-name advisory-options]user@host# set upstream-rate rate
