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.
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 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.
[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-map 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-map cm-1
Switch(config-pmap-c)# set dscp 7
Switch(config-pmap-c)# service-policy port-plcmap-1
Step 23
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.
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.
