Remark CoS to DSCP
Setup > LAN QoS > Remark CoS to DSCP
Remarking CoS to DSCP is an advanced QoS configuration, where the Layer 2 quality
of service field is translated to a Layer 3 QoS field in the packet, so that upstream
routers can make a QoS decision based on the DSCP field set in the packet.
Figure 17: Remark CoS to DSCP
Once you enable CoS to DSCP marking by choosing the check box, you can choose
the appropriate value of the DSCP for a given CoS value.
