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 configure EEM and how to use it to monitor and manage the Cisco
Industrial Ethernet 2000U Series (IE 2000U) and Connected Grid Switches, hereafter referred to as
switch.
Note For complete syntax and usage information for the commands used in this chapter, see the documents

Information About 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
because some problems compromise communication between the switch and the external network
management device. Network availability is improved if automatic recovery actions are performed
without rebooting the switch.
