Configuring QoS
After you have created an output policy map, you attach it to an egress port. See the “Attaching a Traffic
Policy to an Interface” section on page30-35.
Use the no form of the appropriate command to delete an existing policy map or class map or to cancel
the priority queuing or policing for the priority class or the bandwidth setting for the other classes.
This example shows how to use the priority with police commands to configure out-class1 as the
priority queue, with traffic going to the queue limited to 20000 000 bps so that th e pri ori ty qu eu e never
uses more than that. Traffic above that rate is dropped. The other traffic queues are configured as in the
previous example.
Switch(config)# policy-map policy1
Switch(config-pmap)# class out-class1
Switch(config-pmap-c)# priority
Switch(config-pmap-c)# police 200000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class out-class2
Switch(config-pmap-c)# bandwidth percent 50
Switch(config-pmap-c)# exit
Switch(config-pmap)# class out-class3
Switch(config-pmap-c)# bandwidth percent 20
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# service-policy output policy1
Switch(config-if)# exit
Step11 bandwidth {rate | percent value}
or
shape average target bps
Set output bandwidth limits for the policy-map class in kilobits
per second (the range is 64 to 1000000) or percentage of the total
bandwidth (the range is 1 to 100percent).
or
Specify the average class-based shaping rate in bits per second
(the range is 64000 to 1000000000).
Step12 exit Return to policy-map configuration mode.
Step13 exit Return to global configuration mode.
Step14 interface interface-id Enter interface configuration mode for the interface to which you
want to attach the policy.
Step15 service-policy output policy-map-name Attach the policy map (created in Step 3) to the egress interface.
Step16 end Return to privileged EXEC mode.
Step17 show policy-map Verify your entries.
Step18 copy running-config startup-config (Optional) Save your entries in the configuration file.
