## Create an Alarm

To create an alarm, you must configure these parameters:

- Alarm variable (object identifier)

- Alarm sample type

- Alarm interval

- Start up alarm

- Rise or fall threshold values

- Event index

You must create an event table entry before you can create an alarm. For instructions on how to create an event, see Create an Event.

1. Create an alarm for absolute samples.

       SEFOS(config)# rmon alarm 1 1.3.6.1.2.1.16.1.1.1.6.1 20 absolute rising-threshold 500 1 falling-threshold 200 2 owner myTest

2. Create an alarm for delta samples.

       SEFOS(config)# rmon alarm 2 1.3.6.1.2.1.16.1.1.1.7.1 25 delta rising-threshold 200 falling-threshold 100 owner system

3. Review the alarm configuration.

       SEFOS# show rmon alarms

       RMON is enabled
       Alarm 1 is active,  owned by myTest
        Monitors 1.3.6.1.2.1.16.1.1.1.6.1 every 20 second(s)
        Taking absolute samples, last value was 837
        Rising threshold is 200, assigned to event 1
        Falling threshold is 100, assigned to event 2
        On startup enable rising alarm
        Alarm 2 is active,  owned by system
        Monitors 1.3.6.1.2.1.16.1.1.1.7.1 every 25 second(s)
        Taking delta samples, last value was 201
        Rising threshold is 100, assigned to event 1
        Falling threshold is 50, assigned to event 2
