Configuring RMON
This chapter describes how to configure Remote Network Monitoring (RMON) on the Catalyst 2960and
2960-S switches. Unless otherwise noted, the term switch refers to a standalone switch and to a switch
stack.
Note Stacking is supported only on Catalyst 2960-S switches running the LAN base image.
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, see the “System
Management Commands” section in the Cisco IOS Configuration Fundamentals Command Reference,

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 as shown in Figure 28-1.
