Configuring Qos Attributes; Creating A Class Map - Cisco MWR 1941-DC - 1941 Mobile Wireless Router Software Configuration Manual

Chapter 6 Configuring the MWR 1941-DC in a Cell Site DCN

Configuring QoS Attributes

To use QoS on the MWR 1941-DC router in a Cell Site DCN, create a class map that defines the criteria
that a packet much match to be placed in that class and then tell the router the action to take on those
packets that match by creating a policy map. These two components make up the QoS boilerplate and
once you have created the QoS boilerplate, you can assign it to an interface.
The QoS functionality of the MWR 1941-DC router is built on the same code as the Cisco 10000 ESR
Note
(with some exceptions). For more information about the QoS feature, see "Configuring Quality of
Service" (http://www.cisco.com/univercd/cc/td/doc/product/aggr/10000/10ksw/qosos.htm) and the
"Cisco 10000 Series ESR Quality of Service" feature module
(http://www.cisco.com/univercd/cc/td/doc/product/aggr/10000/10kfm/fm_qos.htm), as well as the
"Cisco IOS Quality of Service Solutions Configuration Guide" and the "Cisco IOS Quality of Service
Solutions Command Reference."

Creating a Class Map

For each class map that you want to create, do the following in global configuration mode:
Step 1 Assign a name to your class map.
Router(config)# class-map [match-all | match-any] class_name
Where match-any means a single match rule is sufficient for class membership and match-all means
only those packets that have all the attributes you specify are part of the class.
When you enter the class-map command, you are placed in class map configuration mode.
Describe the characteristics of the packets that are subject to QoS using one or more of the following.
Step 2
Router(config-cmap)# match access-group number
Router(config-cmap)# match ip dscp number
Router(config-cmap)# match ip precedence number
Router(config-cmap)# match input-interface interface-name
Router(config-cmap)# match protocol protocol

Exit class map configuration mode.
Step 3
Router(config-cmap)# exit
OL-11503-01
match access-group specifies access control list (ACL) that a packet must match.
match ip dscp specifies the IP differentiated service code point (DSCP) that a packet must match.
match ip precedence specifies the precedence values (0-7) that a packet must match.
match input-interface specifies the name of the input interface used as a match criterion.
match input-protocol specifies the protocol that a packet must match.
