Chapter 11 Avaya P330 Layer 2 Features

SMON

SMON Overview

SMON is Avaya’s standard-setting switch monitoring technology that has now been adopted as IETF standard RFC 2613. SMON extends the RMON standard to provide the switch monitoring tools and features you need to analyze the switched network and all its components.

SMON provides the basis for top-down network monitoring. Top-down monitoring starts when the you notice particular traffic flow patterns in a global view of the network. The network manager can progressively focus in and find the specific source or sources of the traffic.

Using this method, the amount of information the network manager must assess is kept to a minimum. Top-down monitoring is robust enough to enable control of even the most complex and sophisticated networks.

SMON is an extension of the RMON standard. SMON adds to the monitoring capabilities of RMON in the following ways:

It provides additional tools and features for monitoring in the switch environment.

It allows monitoring of ATM networks that are based on cells rather than packets.

It provides a global view of traffic flow on a network with multiple switches. SMON monitoring provides:

A global view of traffic for all switches on the network

An overall view of traffic passing through a specific switch

Detailed data of the hosts transmitting packets or cells through a switch

An analysis of traffic passing through each port connected to a switch, and

A view of traffic between various hosts connected to a switch.

SMON extends both RMON I for the MAC layer, and RMON 2 for the network layer and higher. SMON monitoring collects and displays data in real-time.

Top-down view of all traffic:

Network view for selected switches

Network view for selected ports

VLAN view

History

In order to use SMON, you need to install the SMON license on the P330 switch and use Avaya MSNM with SMON. See “Basic Switch Configuration“ in the Avaya P330 Installation and Maintenance Guide.

SMON for the network layer is not supported in this version of the P330.
