Understanding Embedded Event Manager - Cisco WS-CBS3032-DEL Software Configuration Manual

Configuring Embedded Event Manager
Embedded Event Manager (EEM) is a distributed and customized approach to event detection and
recovery within a Cisco IOS device. EEM offers the ability to monitor events and take informational,
corrective, or any other EEM action when the monitored events occur or when a threshold is reached.
An EEM policy defines an event and the actions to be taken when that event occurs.
This chapter describes how to use the embedded event manager (EEM) to monitor and manage the switch
and how to configure it. Unless otherwise noted, the term switch refers to a standalone switch and to a
switch stack.
For complete syntax and usage information for the commands used in this chapter, see the switch
command reference for this release and the Cisco IOS Network Management Command Reference. For
the complete EEM document set, see these documents in the Cisco IOS Network Management

Note Beginning with Cisco IOS Release 12.2(55)SE, the EEM feature is supported on the IP base feature set.

Understanding Embedded Event Manager

EEM monitors key system events and then acts on them through a set policy. This policy is a programmed
script that you can use to customize a script to invoke an action based on a given set of events occurring.
The script generates actions such as generating custom syslog or Simple Network Management Protocol
(SNMP) traps, invoking CLI commands, forcing a failover, and so forth. The event management
capabilities of EEM are useful because not all event management can be managed from the switch and
