Example ITM Configuration Integrated Traffic Monitoring

Example ITM Configuration

In the following example, ITM is used to capture network usage information to more accurately determine

network availability and possible congestion problems. In this example, ITM, along with Top Traffic,

provides information about who is using the network, where the network traffic is going, and the peak time

of network usage. These factors allow a study of network patterns and user behavior in order to configure

the network to avoid congestion problems during peak times.

The following illustration is an overview of the configured ITM process.

Figure 4. ITM Configuration Diagram

To capture the desired network information, ITM is enabled on ingress for the ethernet 0/1 interface from

the interface configuration mode. An ACL, named engineering, is specified to help keep the AOS

product’s memory and CPU usage to a minimum, as well as add an extra dimension of network security.

(config-eth 0/1)#ip flow ingress engineering

It is assumed for the purposes of this example that RapidRoute has already been enabled

on your AOS product.
