Configuring RMON Alarms
You can configure RMON alarms on any integer-based SNMP MIB object. The following two types of
SNMP alarms can be configured:
• 32-bit RMON alarm
• 64-bit high-capacity RMON alarm
To configure the 32-bit RMON alarm, use the rmon alarm command. To configure the 64-bit
high-capacity RMON alarm, use the rmon hcalarm command.
You can optionally specify the following parameters:
• The event-number for 32-bit and 64-bit RMON alarms. The event number triggers the alarm if the
rising or falling threshold exceeds the specified limit. Use the rising-event or falling-event
parameters to specify the event-number value. The range is from 0 to 65535. If no value is specified,
event 0 is the default.
• The rising and falling threshold value for 32-bit RMON alarms. Use the rising-threshold value
command or the falling-threshold value command. The range is from – 2147483647 to 214748364.
• The rising threshold value for 64-bit RMON alarms. Use the rising-threshold-high value command
to configure the upper 32 bits of the 64-bit rising threshold value. Use the rising-threshold-low
value command to configure the lower 32 bits of the 64-bit rising threshold value. The range is from
0 to 4294967295.
• The falling threshold value for 64-bit RMON alarms. Use the falling-threshold-high value
command to configure the upper 32 bits of the 64-bit falling threshold value. Use the
falling-threshold-low value command to configure the lower 32 bits of the 64-bit falling threshold
value. The range is from 0 to 4294967295.
• The owner of the alarm.
Ensure you have configured an SNMP user and enabled SNMP notifications (see the “Configuring
SNMP” section on page 1-5).
