Configuring Remote Monitoring
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.
Configuring and Managing RMON
Both alarms and events are configurable RMON parameters.
• Alarms allow you to monitor 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 are paired with events; the alarm triggers an event, which can
generate a log entry or an SNMP trap.
• Events determine 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. You must define the events before an alarm can be
configured. If you do not configure the RMON event first, you will receive an error when you configure
the alarm settings.
By default, no RMON alarms and events are configured and RMON collection statistics are not enabled.
Configuring RMON events
You can add or remove an event in the RMON event table that is associated with an RMON alarm
number.
To configure RMON events, perform the following steps from privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode.
switch# configure terminal
2. Configure the RMON event.
switch(config)# rmon event 27 description Rising_Threshold log owner john_smith
trap syslog
3. Return to privileged EXEC mode.
switch(config)# end
4. Save the running-config file to the startup-config file.
switch# copy running-config startup-config
