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 group statistics collection

You can collect RMON group statistics on an interface. RMON alarms and events must be configured for you to display collection statistics. By default, RMON group statistics are not enabled. The statistics are measured by the probe for each monitored interface on the switch. These statistics include, but aren’t limited to the following items:

•Packets dropped and sent

•Bytes sent (octets)
