Configuring Last-Mile QoS

Configuring Last-Mile QoS

When implementing traffic shaping, the device uses last-mile QoS to deduct excessive link costs, such as the ATM cell header and Ethernet frame header.This helps prevent the congestion when the downstream traffic of the device exceeds the line capacity of the DSLAM.

Context

When the NE40E functions as a BRAS, you can configure last-mile QoS for it so that the NE40E can perform QoS shaping more accurately by deducting extra costs, such as the cost of the ATM cell header. This helps to prevent the congestion that occurs when the downstream traffic of the NE40E exceeds the line capacity of the DSLAM.

You can configure last-mile QoS in both the interface view and the AAA domain view. The configuration in the AAA domain view takes effect for only the L2TP service. When last-mile QoS is configured in the AAA domain view and the interface view concurrently, only the configuration in the AAA domain view takes effect.

Pre-configuration Tasks

Before configuring last-mile QoS, complete the following task:

  • Configuring the BRAS function for the NE40E so that users can successfully access the network
