Avaya P120 SMON User Guide 2
SMON Overview
RMON has two levels:
• RMON I analyzes the MAC layer (Layer 2 in the OSI seven-layer
model).
• RMON II analyzes the upper layers (Layers 3 and above).
RMON is an industry standard that Avaya Inc. and other companies have
adopted in their network management applications. SMON takes the
RMON standard and extends it to the switching environment.
What is SMON
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 provides a global view of traffic flow in a network with multiple
switches.
Device SMON extends RMON I for the MAC layer, and AnyLayer SMON
extends RMON II for the network layer and above. SMON monitoring
collects and displays data in real-time.
Using SMON monitoring, you can get:
• A global view of traffic for all switches on the network.
• An overall view of traffic passing through a specific switch.
• Detailed data about the hosts transmitting packets through a
switch.
• An analysis of traffic passing through each port connected to a
switch.
• A view of traffic between various hosts connected to a switch.
Overview of SMON
SMON is an RMON-compliant network management suite that
implements the SMON extensions to RMON. SMON works with the other
components of Avaya MultiService Network Manager to provide a full
spectrum of in-depth monitoring of switch traffic and network
performance.
