– owner string: (Optional) specifies an owner for the alarm, this setting is the alarmOwner objectin the alarmTable of the RMON MIB. Default is a null-terminated string.Example of the rmon alarm CommandTo disable the alarm, use the no form of the command.The following example configures RMON alarm number 10. The alarm monitors the MIB variable1.3.6.1.2.1.2.2.1.20.1 (ifEntry.ifOutErrors) once every 20 seconds until the alarm is disabled, and checks therise 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 counterincrease of 15 or more (such as from 100000 to 100015). The alarm then triggers event number 1, whichis configured with the RMON event command. Possible events include a log entry or an SNMP trap. If the1.3.6.1.2.1.2.2.1.20.1 value changes to 0 (falling-threshold 0), the alarm is reset and can be triggered again.Dell(conf)#rmon alarm 10 1.3.6.1.2.1.2.2.1.20.1 20 delta rising-threshold15 1 falling-threshold 0 1 owner nms1Configuring an RMON EventTo add an event in the RMON event table, use the rmon event command in GLOBAL CONFIGURATIONmode.• Add an event in the RMON event table.CONFIGURATION mode[no] rmon event number [log] [trap community] [description string] [ownerstring]– number: assign an event number in integer format from 1 to 65535. The number value must beunique in the RMON event table.– log: (Optional) enter the keyword log to generate an RMON event log, it sets the eventType toeither log or log-and-snmptrap in the RMON event table. The default is None.– trap community: (Optional) enter the keyword trap and SNMP community string to generateSNMP traps for an RMON event entry, it sets the eventType to either snmptrap or log-and-snmptrap in the RMON event table. This option generates syslog as well along with SNMP traps.– description string: (Optional) specifies a description of the event, which is identical to theevent 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 theeventTable of the RMON MIB. Default is a null-terminated string.Example of the rmon event CommandTo 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 “HighifOutErrors”, and generates a log entry when an alarm triggers the event. The user nms1 owns the rowthat is created in the event table by this command. This configuration also generates an SNMP trap whenthe event is triggered using the SNMP community string “eventtrap”.Dell(conf)#rmon event 1 log trap eventtrap description “High ifOutErrors” ownernms1Remote Monitoring (RMON) 699
