    Adjusting the Data Rate Reported by ANCP for DSL Lines Overview

    When a DSLAM calculates the data rate, it ignores additional headers on the DSL line. When ANCP reports the upstream data rate (L2C Type 4 Sub-type 129) or the downstream data rate (L2C Type 4 Sub-type 130), it includes the headers in its calculation and therefore reports a slightly higher value. This discrepancy causes the QoS shaping rate to be slightly higher than the actual rate.

    You can set a percentage value ANCP applies to the data rate to generate a more accurate value that is reported to AAA whenever AAA requests the data rate from ANCP.

    ANCP does not report the calculated data rate to RADIUS or to L2TP.
