•
event-number: event number to trigger when the rising threshold exceeds its limit. This value is
identical to the alarmRisingEventIndex in the alarmTable of the RMON MIB. If there is no
corresponding rising-threshold event, the value should be zero.
•
falling-threshold value: value at which the falling-threshold alarm is triggered or reset. For
the rmon alarm command, this setting is a 32-bits value, for the rmon hc-alarm command this
setting is a 64 bits value.
•
event-number: event number to trigger when the falling threshold exceeds its limit. This value is
identical to the alarmFallingEventIndex in the alarmTable of the RMON MIB. If there is no
corresponding falling-threshold event, the value should be zero.
•
owner string: (Optional) specifies an owner for the alarm, this setting is the alarmOwner object in
the alarmTable of the RMON MIB. Default is a null-terminated string.
Example of the rmon alarm Command
To disable the alarm, use the no form of the command.
The following example configures RMON alarm number 10. The alarm monitors the MIB variable
1.3.6.1.2.1.2.2.1.20.1 (ifEntry.ifOutErrors) once every 20 seconds until the alarm is disabled, and checks the rise
or fall of the variable. The alarm is triggered when the 1.3.6.1.2.1.2.2.1.20.1 value shows a MIB counter increase
of 15 or more (such as from 100000 to 100015). The alarm then triggers event number 1, which is configured
with the RMON event command. Possible events include a log entry or an SNMP trap. If the
1.3.6.1.2.1.2.2.1.20.1 value changes to 0 (falling-threshold 0), the alarm is reset and can be triggered again.

Configuring an RMON Event
To add an event in the RMON event table, use the rmon event command in GLOBAL CONFIGURATION
mode.
•
Add an event in the RMON event table.
CONFIGURATION mode
[no] rmon event number [log] [trap community] [description string] [owner
string]
•
number: assigned event number, which is identical to the eventIndex in the eventTable in the RMON
MIB. The value must be an integer from 1 to 65,535 and be unique in the RMON Event Table.
•
log: (Optional) generates an RMON log entry when the event is triggered and sets the eventType in
the RMON MIB to log or log-and-trap. Default is no log.
•
trap community: (Optional) SNMP community string used for this trap. Configures the setting of
the eventType in the RMON MIB for this row as either snmp-trap snmptrap or log-and-trap. This
value is identical to the eventCommunityValue in the eventTable in the RMON MIB. Default is public.
•
description string: (Optional) specifies a description of the event, which is identical to the
event description in the eventTable of the RMON MIB. The default is a null-terminated string.
•
owner string: (Optional) owner of this event, which is identical to the eventOwner in the
eventTable of the RMON MIB. Default is a null-terminated string.
Example of the rmon event Command
To disable RMON on the interface, use the no form of this command.
In the following example, the configuration creates RMON event number 1, with the description "High
ifOutErrors", and generates a log entry when an alarm triggers the event. The user nms1 owns the row that is
