RMON overview
Remote monitoring (RMON) is an Internet Engineering Task Force (IETF) standard monitoring
specification that allows various network agents and console systems to exchange network
monitoring data. The RMON specification defines a set of statistics and functions that can be
exchanged between RMON-compliant console managers and network probes. As such, RMON
provides you with comprehensive network-fault diagnosis, planning, and performance-tuning
information.
RMON configuration and management
Alarms and events are configurable RMON parameters:
• Alarms—Monitors a specific management information base (MIB) object for a specified
interval, triggers an alarm at a specified value (rising threshold), and resets the alarm at
another value (falling threshold). Alarms can be used with events; the alarm triggers an event,
which can generate a log entry or an SNMP trap.
• Events—Determines the action to take when an event is triggered by an alarm. The action can
be to generate a log entry, an SNMP trap, or both.
Default RMON configuration
By default, no RMON alarms and events are configured and RMON collection statistics are not
enabled.
Configuring RMON settings
To configure RMON alarms and events, perform the following steps from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
switch#configure terminal
