Figure19-1 Remote Monitoring Example
The switch supports these RMON groups (defined in RFC 1757):
•Statistics (RMON group 1)—Collects Ethernet, Fast Ethernet, and Gigabit Ethernet statistics on an
interface.
•History (RMON group 2)—Collects a history group of statistics on Ethernet, Fast Ethernet, and
Gigabit Ethernet interfaces for a specified polling interval.
•Alarm (RMON group 3)—Monitors a specific 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.
•Event (RMON group 9)—Determines the action to take when an event is triggered by an alarm. The
action can be to generate a log entry or an SNMP trap.
Because switches supported by this software release use hardware counters for RMON data processing,
the monitoring is more efficient, and little processing power is required.
Configuring RMONThis section describes how to configure RMON on your switch. It contains this configuration
