Cisco Embedded Event Manager (EEM)
The Cisco Embedded Event Manager, or Cisco EEM, is a software component of Cisco IOS, IOS-XR, and NX-OS that provides real-time network event detection and onboard automation.
EEM allows you to automate tasks, perform minor enhancements, and create workarounds.
It can make life easier for network operators by tracking and classifying events that take place on a network device and providing action options for those events.
