Configuring QoS Attributes

Creating a Policy Map

To create a policy map, do the following in global configuration mode:
Step 1 Assign a name to your policy map.
Router(config)# policy-map policy_name
When you enter the policy-map command, you are placed in policy map configuration mode.
Associate the policy map with a class map.
Step 2
Router(config-pmap)# class class_name
Specify the same class_name as you did in
command, you are placed in class submode of the policy-map configuration mode.
Describe the QoS actions you want the router to perform when the router encounters a packet that has
Step 3
the characteristics described by the class map. Use one or more of the following commands:
Router(config-pmap-c)# priority percent number
Router(config-pmap-c)# bandwidth percent number
Router(config-pmap-c)# queue-limit number
Router(config-pmap-c)# priority rate-in-kbps
Router(config-pmap-c)# shape {average | peak} cir [bc] [be]
Router(config-pmap-c)# shape max-buffers number-of-buffers

priority percent gives priority to a class of traffic belonging to a policy map and specifies that a
certain percentage of the available bandwidth should be reserved for this class.
bandwidth percent specifies the bandwidth allocated for a class belonging to a policy map.
queue-limit specifies the maximum number of packets the queue can hold for a class policy
configured in a policy map.
priority enables low-latency priority queuing, which allows you to assign a specified share of the
link bandwidth to one queue that receives priority over all others. Low-latency priority queueing
minimizes the packet-delay variance for delay-sensitive traffic, such as live voice and video.
shape and shape max-buffers are used with class-based weighted fair queuing (CB-WFQ), which
allows you to control the traffic going out an interface in order to match its transmission to the speed
of the remote target interface.
The bandwidth percent and priority percent commands cannot be used in the same
