AnyLayer SMON Tools

The following sections describe the AnyLayer SMON tools for Avaya

C460:

•Protocol Distribution Overview - Describes how the C460 provides detailed information on protocol traffic passing through the router module.

•DSCP Overview - Describes how the C460 provides detailed information on DSCP tagged traffic passing through the router module.

Protocol Distribution Overview

Protocol Distribution provides you with details about the protocols routed by an Avaya C460 routing module, and tracks the distribution of traffic through the device among various network and application layer protocols. Protocol Distribution collects all information in real-time, and displays it in a variety of powerful and easy to use graphic formats.

Protocol Distribution stores all data recently collected from the device. Protocol Distribution also allows you to save collected information in reports. You can learn what is normal and abnormal behavior for your specific network by viewing the reports and analyzing changes in your network’s traffic. This can help you discover problems in your network configuration. In general, the Protocol Distribution tool can help you see things that become apparent over time from a high-level view. For more information on C460 implementation of Protocol Distribution, refer to Chapter 9, Using Protocol Distribution and DSCP Statistics.

DSCP Overview

Protocol Distribution for the Avaya C460 router modules includes monitoring of DSCP tagged traffic. DSCP is an extension of IP which provides a method of encoding QoS (Quality of Service) information in the IP header of traffic. This enables you to change the priority of packets to conform to standards for applications such as Voice over IP. Protocol Distribution for Avaya C460 router modules provides graphical representations of IP traffic with non-zero DSCP headers and IP traffic with zero DSCP headers.

A DSCP value between 0 and 63 is added to the IP header of data packets. For more information on the implementation of DSCP, refer to “Viewing DSCP Statistics” on page 72.
