Introduction

The following information provides an example for configuring rate limiting.

Prerequisites

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of ACL and QoS.

Example: Configuring rate limiting

Network configuration

As shown in Figure 1, the router serves as the egress router on the enterprise network and uses a single WAN interface with a fixed public address to connect to the Internet. Configure rate limiting to meet the following requirements:

·     Limit the download rate of each host in the IP address range of 192.168.30.2 to 192.168.30.254 to 1000 kbps.

·     Apply rate limiting to the interface that connects to the public network.
