The following example configures an RMON alarm using the rmon alarm command.
FTOS(conf)#rmon alarm 10 1.3.6.1.2.1.2.2.1.20.1 20 delta rising-threshold 15 1 fall-
ing-threshold 0 owner nms1
The above 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 a 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.
Configure an RMON event
To add an event in the RMON event table, use the rmon event command in GLOBAL CONFIGURATION
mode. To disable RMON on the interface, use the
no form of this command:
The following example shows the
rmon event command.
FTOS(conf)#rmon event 1 log trap eventtrap description “High ifOutErrors” owner nms1
The above configuration example creates RMON event number 1, with the description “High ifOutErrors”,
and generates a log entry when the event is triggered by an alarm. The user nms1 owns the row that is
created in the event table by this command. This configuration also generates an SNMP trap when the
event is triggered using the SNMP community string “eventtrap”.
Command Syntax Command Mode Purpose
[no] rmon event number [log]
[trap community]
[description string] [owner
string]
CONFIGURATION 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, the value must
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 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. 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.
