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 tells how to use EEM and how to configure it on a Catalyst 3750-X or 3560-X switch.

Unless oth

erwise noted, the term switch refers to a standalone switch or a Catalyst 3750-X switch stack.

Note The EEM feature is supported only if the IP services feature set is installed on the switch.

For complete syntax and usage inf

ormation 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

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
