# Configuring Traffic Classes on Multiclass MLPPP Interfaces

You can configure mapping of QoS traffic classes to multilink classes. The best-effort QoS traffic class is mapped to multilink class 0 by default.

To configure mapping of QoS traffic classes to multilink classes:

- Specify the QoS traffic classes to be mapped to the multilink classes.

  - To map QoS traffic classes to multilink classes in a dynamic profile:

    host1(config-profile)#ppp multilink multiclass traffic-class best-effort voice otherData video

  - To map QoS traffic classes to multilink classes in a static MLPPP interface:

    host1(config-if)#ppp multilink multiclass traffic-class best-effort voice otherData video

  | Note: You must include the best-effort traffic class in the ppp multilink multiclass traffic-class command, or the command fails.
