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. Dell(conf)#rmon alarm 10 1.3.6.1.2.1.2.2.1.20.1 20 delta rising-threshold 15 1 falling-threshold 0 1 owner nms1 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: assign an event number in integer format from 1 to 65535. The number value must be unique in the RMON event table. - log: (Optional) enter the keyword log to generate an RMON event log, it sets the eventType to either 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 generate SNMP traps for an RMON event entry, it sets the eventType to either snmptrap or log-andsnmptrap 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 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 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". Dell(conf)#rmon event 1 log trap eventtrap description "High ifOutErrors" owner nms1 Configuring RMON Collection Statistics To enable RMON MIB statistics collection on an interface, use the RMON collection statistics command in INTERFACE CONFIGURATION mode. • Enable RMON MIB statistics collection.
