Objective

The objective of this document is to configure the alarms on the switch for an event which needs to be monitored and alarmed to the network administrators.

Note: Alarms can be configured only if there is a RMON event configured on the switch. For more information on how to configure a RMON event, refer to the article RMON Events on 200/300 Series Managed Switches.
