Chapter 25 Configuring Quality of Service
Configuring Quality of Service
• While QoS is enabled on the SVI interface, the Cisco MWR 2941 supports only DSCP-to-CoS
remarking on the SVI interface.
• Because the Cisco MWR 2941 supports DSCP-to-CoS mapping via an SVI interface, operators must
manage route paths to ensure that all incoming traffic from a multilink interface is forwarded to a
VLAN on which the remarking occurs on the egress side of the VLAN interface.
• Policy-map counters are not updated for the egress SVI interface.
• Operators can only view DSCP-to-COS remarking in a neighbor router (or Traffic Generator) that
is connected to the Cisco MWR 2941 over the SVI interface.
To implement MLPP Ingress DSCP-to-CoS marking, complete the tasks in the following sections:
• Creating and Configuring a Mapping Table, page 25-17
• Configuring a Policy Map and Associating the DSCP-to-COS Mapping Table, page 25-18
• Attaching the Policy Map to the SVI Interface, page 25-19
Creating and Configuring a Mapping Table
To create a mapping table in which you map DSCP values to COS values, complete the following steps:
Command Purpose
Step 1
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 2
table-map name
Example:
Router(config)# table-map
DSCP-to-COS-marking
Creates a table map using the specified name and enters tablemap
configuration mode.
Step 3
map from DSCP-value to COS-value
Example:
Router(config-tablemap)# map from
46 to 4
Maps the DSCP value to the COS value.
Note On the Cisco MWR 2941, in the table map, the map default sub
configuration command is not supported for values not found in
the table map. You must specify specific DSCP values to map to
COS values.
Step 4
exit
Example:
Router(config-tablemap)# end
Router(config)#
Exits tablemap configuration mode.
