• Policy. Defines the QoS attributes for one or more traffic classes. An example of an attribute is the
ability to mark a packet at ingress. The 7000 Series Managed Switch supports a Traffic Conditions
Policy. This type of policy is associated with an inbound traffic class and specifies the actions to be
performed on packets meeting the class rules:
– Marking the packet with a given DSCP code point, IP precedence, or CoS
– Policing packets by dropping or re-marking those that exceed the class's assigned data rate
– Counting the traffic within the class
• Service. Assigns a policy to an interface for inbound traffic
