Chapter 19: QoS Configuration Guide

prioritization, traffic rate limiting is a mechanism to control bandwidth usage of incoming traffic on a per flow basis.

A traffic profile is used to define the traffic characteristics before an upper limit is assigned. The traffic profile is created using one or more ACLs which can utilize any combination of the parameters supported in the IP ACL. A rate limiting profile can then be defined by using the ACL and traffic rate limitations. A single rate limiting profile can have multiple ACLs to define different traffic profiles and traffic rate limitations. When there are multiple traffic profiles, a sequence number is used to identify the order in which the profiles are applied. You can define the action taken on the traffic that exceeds the upper limit: either drop the packets or reset the priority of the traffic. The rate limiting profile is then applied to a logical IP interface.

To define a rate limit profile and apply the profile to an interface, enter the following commands in Configure mode:

Define a rate limit profile.	rate-limit <name> input acl <acl list> rate
	<rate-limit>exceed-action drop-packetsset-
	priority-lowset-priority-mediumset-
	priority-high [sequence <number>]
Apply a rate limit profile to an	rate-limit <name> apply interface
interface.	<interface>all

Note: You cannot use non-IP ACLs for rate limit profiles.
