Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network engineer wants to configure a Cisco router to automatically execute a series of commands if a specific condition is met, such as an interface going down or CPU utilization exceeding a threshold. This automation should help in proactive troubleshooting and self-healing. Which Cisco feature is designed for this event-driven automation?
- AIP SLA
- BEmbedded Event Manager (EEM)
- CSyslog
- DSNMP Traps
Show answer & explanationAnswer & explanation
Correct answer: B. Embedded Event Manager (EEM)
Embedded Event Manager (EEM) is a powerful and flexible feature that allows Cisco devices to monitor events and react to them by executing pre-defined actions, making it ideal for event-driven automation and self-healing.
Why the other options are wrong
- A. IP SLA generates synthetic traffic to measure network performance, not for event-driven automation or command execution based on device conditions.
- C. Syslog sends log messages to a server for monitoring and analysis, but it does not perform automated actions on the device based on events.
- D. SNMP Traps are used to send notifications to a network management system when an event occurs, but they do not execute commands on the device itself for automation.
Embedded Event Manager (EEM)
Embedded Event Manager (EEM) is a flexible and powerful feature on Cisco devices that allows for event detection and automated, policy-driven actions, enabling self-healing and proactive troubleshooting.
- Event-driven automation.
- Monitors various events (interface status, syslog, SNMP).
- Executes predefined actions (CLI commands, Tcl scripts).
- Enhances network resilience and reduces manual intervention.
- Uses 'applet' configurations.
Memory trick: For events that happen, EEM can snap in, and commands begin.
