Users Guide

• Queuing policies must be applied in the output direction on physical interfaces or on system-qos mode.
• Application type policy-map must be applied on system-qos mode.
When a policy is applied on system, the policy is eective on all the ports in the system. However, interface level policy gets
precedence over system level policy.
Class-map conguration
You can implement classication or ltering packets into various trac classes based on a packet match criteria using class-maps. OS10
allows you to create class-maps to separate packets based on a specic match criteria. You can congure three types of class-maps—
control-plane, qos (default), and queueing.
• Create a class-map, and congure a name for the class-map in CONFIGURATION mode.
class-map [type [control-plane | qos | queuing]] [match-all | match-any]class-map-name
– qos—Creates a QoS class-map
– queuing—Creates a queuing class-map
– control-plane—Creates a control-plane class-map
– match-all | match-any—Sets match-all or match-any as match lter, with match-any as the default
– class-map-name—Enter a class-map name - up to 32 characters
NOTE: If you create a class-map without entering the class-map type, qos is automatically set as the default class-map type.
Congure class-map
OS10(config)# class-map type qos match-any cmap
View class-map
OS10(config)# do show class-map
Class-map (qos): cmap (match-any)
Policy-map conguration
Congure policy-maps to create a named object that represents a set of policies that apply to a set of trac classes. You can congure
three types of policy-maps—control-plane, qos (default), and queuing.
1 Create a policy-map, and congure a name for the policy-map in CONFIGURATION mode, up to 32 characters.
policy-map [type {qos | queuing | control-plane}] policy-map-name
• qos—Creates a QoS type policy-map.
• queuing—Creates a queuing type policy-map.
• control-plane—Creates a control-plane type policy-map.
2 Associate a policy-map with a class-map in POLICY-MAP mode.
class class-name
After creating policy-maps and associating the policy-maps with class-maps you can congure shaping, marking, metering, and other QoS
features - see Mark trac and Meter trac.
Create class-map C1
OS10(config)# class-map c1
OS10(conf-cmap-qos)# match cos 1
Show class-map
OS10(conf-cmap-qos)# do show class-map type qos c1
Class-map (qos): c1 (match-cos)
