Configuring RMON
This chapter describes how to configure Remote Network Monitoring (RMON) on your Catalyst 3550
switch. RMON is a standard monitoring specification that defines a set of statistics and functions that
can be exchanged between RMON-compliant console systems and network probes. RMON provides you
with comprehensive network-fault diagnosis, planning, and performance-tuning information.
Note For complete syntax and usage information for the commands used in this chapter, refer to the Cisco IOS

Understanding RMON
RMON is an Internet Engineering Task Force (IETF) standard monitoring specification that allows
various network agents and console systems to exchange network monitoring data. You can use the
RMON feature with the Simple Network Management Protocol (SNMP) agent in the switch to monitor
all the traffic flowing among switches on all connected LAN segments.
