RMON Commands 317rmon alarmThe rmon alarm Global Configuration mode command configures alarm conditions. Use the no form ofthis command to remove an alarm.Syntax• rmon alarm index variable interval rthreshold fthreshold revent fevent [type type] [startup direction][owner name]• no rmon alarm index• index — The alarm index. (Range: 1 - 65535)• variable — The object identifier of the particular variable to be sampled.• interval — The interval in seconds over which the data is sampled and compared with the risingand falling thresholds. (Range: 1 - 2147483648)• rthreshold — Rising Threshold. (Range: 1 - 4294967295)• fthreshold — Falling Threshold. (Range: 1 - 4294967295)• revent — The Event index used when a rising threshold is crossed. (Range: 1 - 65535)• fevent — The Event index used when a falling threshold is crossed. (Range: 1 - 65535)• type type — The sampling method for the selected variable and calculating the value to becompared against the thresholds. If the method is absolute, the value of the selected variable iscompared directly with the thresholds at the end of the sampling interval. If the method is delta,the selected variable value at the last sample is subtracted from the current value, and thedifference compared with the thresholds.• startup direction — The alarm that may be sent when this entry is first set to valid. If the firstsample (after this entry becomes valid) is greater than or equal to the rthreshold, and direction isequal to rising or rising-falling, then a single rising alarm is generated. If the first sample (afterthis entry becomes valid) is less than or equal to the fthreshold, and direction is equal to falling orrising-falling, then a single falling alarm is generated.• owner name — Enter a name that specifies who configured this alarm. If unspecified, the name isan empty string.Default ConfigurationThe following parameters have the following default values:• type type — If unspecified, the type is absolute.• startup direction — If unspecified, the startup direction is rising-falling.Command ModeGlobal Configuration mode.5400_CLI.book Page 317 Wednesday, December 17, 2008 4:33 PM
