Chapter 1 Configuring Embedded Event Manager
Understanding Embedded Event Manager
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.
Figure 1-1 shows the relationship between the EEM server, the core event publishers (event detectors),
and the event subscribers (policies). The event publishers screen events and when there is a match on an
event specification that is provided by the event subscriber. Event detectors notify the EEM server when
an event occurs. The EEM policies then implement recovery based on the current state of the system and
the actions specified in the policy for the given event.

See the EEM Configuration for Cisco Integrated Services Router Platforms Guide for examples of EEM
deployment.
