Chapter 1 Configuring QoS
Configuring Standard QoS
To delete an existing policy map, use the no policy-map policy-map-name global configuration
command. To delete an existing class map, use the no class class-map-name policy-map configuration
command.
To return to the untrusted state in a policy map, use the no trust policy-map configuration command. To
remove an assigned DSCP or IP precedence value, use the no set { dscp new-dscp | ip precedence
new-precedence } policy-map configuration command.
To remove an existing policer in an interface-level policy map, use the no police rate-bps burst-byte
[ exceed-action { drop | policed-dscp-transmit }] policy-map configuration command. To remove the
hierarchical policy map and port associations, use the no service-policy input policy-map-name
interface configuration command.
This example shows how to create a hierarchical policy map:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# access-list 101 permit ip any any
Switch(config)# class-map cm-1
Switch(config-cmap)# match access 101
Switch(config-cmap)# exit
Switch(config)# exit
Switch#
Switch#
This example shows how to attach the new map to an SVI:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# class-map cm-interface-1
Switch(config-cmap)# match input gigabitethernet3/0/1 - gigabitethernet3/0/2
Switch(config-cmap)# exit
Switch(config)# policy-map port-plcmap
Switch(config-pmap)# class cm-interface-1
Switch(config-pmap-c)# police 900000 9000 exc policed-dscp-transmit
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# policy-map vlan-plcmap
Switch(config-pmap)# class cm-1
Switch(config-pmap-c)# set dscp 7
Switch(config-pmap-c)# service-policy port-plcmap-1
Step 24
service-policy input policy-map-name Specify the VLAN-level policy-map name, and apply it to the SVI.
Repeat the previous step and this command to apply the policy map to
other SVIs.
If the hierarchical VLAN-level policy map has more than one
interface-level policy map, all class maps must be configured to the
same VLAN-level policy map specified in the
service-policy
policy-map-name command.
Step 25 end Return to privileged EXEC mode.
Step 26 show policy-map [ policy-map-name [ class
class-map-name ]]
or
show mls qos vlan-based

Step 27
