Avaya C460 SMON User Guide 9
SMON Overview
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.
