What Is Smon; Switch Monitoring - Avaya M770 User Manual

Chapter 1
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:
SMON extends both RMON I for the MAC layer, and RMON II for the
network layer and above. SMON monitoring collects and displays data in
real-time.
Using SMON monitoring, you can get:

Switch Monitoring

Effective switch management requires a comprehensive monitoring
mechanism. RMON monitoring is not sufficient for switches. RMON
probes can only be used to monitor and analyze a single segment. When
you deploy a switch in the network, there are additional components in
the network that can not be monitored using RMON, such as switch
ports, VLAN, and statistics for all ports.
SMON meets this challenge by extending RMON to the switched
network. The SMON extensions of RMON allow the network
administrator to analyze the switched network and all of its components.
