Configuring RMON alarms

Alarms are useful when the network administrator needs to know when the value of some variable goes out of range. RMON alarms can be defined on any MIB variable that resolves to an integer value. In other words, string variables (such as system description) cannot be used as alarm variables.

All alarms share the following characteristics:

• An upper and lower threshold value defined on it
• A corresponding rising and falling event
• An alarm interval or polling period

When alarms are "fired," or activated, you can view the activity in a log or a trap log, or you can create a script to notify you by beeping a console, sending e-mail, or calling a pager.
