How can you limit bandwidth per IP address on cisco router 1811?

To limit bandwidth per IP address on a Cisco 1811 router, you can use the Class-Based Quality of Service (CBQoS) feature. First, define a class map to match the specific IP address or range, then create a policy map to specify the bandwidth limit for that class. Finally, apply the policy map to the appropriate interface using the service-policy command. This setup allows you to effectively manage and allocate bandwidth among different IP addresses as needed.
