Integrated Traffic Monitoring Configuring ITM and Top Traffic Using the CLI

Configuring ITM and Top Traffic Using the CLI

Both ITM and Top Traffic can be configured using the CLI.

Enabling ITM Using the CLI

To enable ITM on a specific interface, enter the interface configuration mode from the Global

configuration mode and use one of the two following commands:

(config-interface)#ip flow ingress

(config-interface)#ip flow egress

Ingress and egress parameters specify which traffic is to be monitored. Ingress, the most commonly used

logging feature, specifies that incoming traffic is monitored, and egress specifies that forwarded or

outgoing traffic is monitored. Both ingress and egress traffic can be monitored on an interface, depending

on the desired configuration. Use the no form of these commands to disable the traffic monitoring for

either incoming or outgoing traffic, as specified.

Both commands include an optional parameter for ACL traffic filtering. When including an ACL, the

command requires an ACL name. The command appears as follows:

(config-interface)#ip flow ingress <name>

In this form, <name> is the name of a previously created ACL. Using the no command disables traffic

monitoring on the interface and removes the association between a specific ACL and traffic monitoring.

Simply enabling ITM on an interface results in using the default values for all user-configurable

parameters. The default values are described in the following table:

To avoid confusion, it should be noted that the CLI commands configure Top Traffic with

“Top Talkers” commands.

For more information regarding the creation of ACLs, refer to page 5 of Configuring

Policy Based Routing available on the AOS Documentation CD shipped with your AOS

product, or available on the Web at www.adtran.com.
