Chapter 23 Configuring QoS

Configuring Standard QoS

This example shows how to create a policy map and attach it to an ingress interface. In the configuration,
the IP standard ACL permits traffic from network 10.1.0.0. For traffic matching this classification, the
DSCP value in the incoming packet is trusted. If the matched traffic exceeds an average traffic rate
of 5000000 bps and a normal burst size of 8192 bytes, its DSCP is marked down to a value of 10 and sent.

Switch(config)# access-list 1 permit 10.1.0.0 0.0.255.255

Switch(config)# class-map ipclass1

Switch(config-cmap)# match access-group 1

Switch(config-cmap)# exit

Switch(config)# policy-map flow1t

Switch(config-pmap)# class ipclass1

Switch(config-pmap-c)# police 5000000 8192 exceed-action dscp 10

Switch(config-pmap-c)# exit

Switch(config-pmap)# exit

Switch(config)# interface gigabitethernet0/17

Switch(config-if)# switchport mode access

Switch(config-if)# service-policy input flow1t

This example shows how to create a Layer 2 MAC ACL with two permit statements and attach it to an
ingress interface. The first permit statement allows traffic from the host with MAC
address 0001.0000.0001 destined for the host with MAC address 0002.0000.0001.

Switch(config)# mac access-list extended maclist1

Switch(config-ext-mac)# permit host 0001.0000.0001 host 0002.0000.0001

Switch(config-ext-mac)# exit

Switch(config)# mac access-list extended maclist2

Switch(config-ext-mac)# permit host 0001.0000.0003 host 0002.0000.0003

Switch(config-ext-mac)# exit

Switch(config)# class-map macclass1

Switch(config-cmap)# match access-group name maclist1

Switch(config-cmap)# exit

Switch(config)# policy-map macpolicy1

Switch(config-pmap)# class macclass1

Switch(config-pmap-c)# set ip dscp 56

Switch(config-pmap-c)# exit

Switch(config-pmap)# class macclass2 maclist2

Switch(config-pmap-c)# set ip dscp 48

Switch(config-pmap-c)# exit

Switch(config-pmap)# exit

Switch(config)# interface gigabitethernet0/17

Switch(config-if)# switchport mode trunk

Switch(config-if)# mls qos trust cos

Switch(config-if)# service-policy input macpolicy1

Configuring CoS Maps

This section describes how to configure the CoS maps:

Configuring the DSCP-to-CoS Map, page 23-33

All the maps are globally defined.
