Note The Cisco MWR 2941 does not support all of the commands described in the IOS Release 15.0S
documentation.
Configuring MLPPP Ingress DSCP-to-COS Marking
Cisco MWR 2941 Release 3.5 introduces support for Multilink PPP (MLPPP) Ingress Differentiated
Services Code Point (DSCP) marking, With this support, operators can map DSCP bits on the ingress
MLPPP interface to a configurable class of service (CoS) 802.1p bits on an egress switch virtual
interface (SVI) interface.
Therefore, the Cisco MWR 2941 does not support the DSCP remarking on multilink interface directly,
but implements the DSCP-to-CoS mapping on a switch virtual interface (SVI) interface using table maps
attached to ingress policies that correlate specific DSCP to specific CoS values.
When implementing DSCP-to-CoS mapping on the Cisco MWR 2941, operators use table maps to
correlate specific DSCP to specific CoS values and attach to an input policy using the set qos-group
command. When the set qos-group policy map configuration command is configured, the assigned QoS
group identification is used in an output policy with no mark or change to the packet.
For detailed information about table maps and policies, see the QoS: Classification Configuration Guide.

Usage Notes
• The Cisco MWR 2941 implements MLPPP DSCP-to-CoS remarking using an SVI interface.
• The Cisco MWR 2941 supports automatic mapping of ingress DSCP via multilink to CoS over a
VLAN interface.
• The Cisco MWR 2941 supports IPv4 DSCP-to-CoS mapping only; it does not support IPv6
mapping.
