Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2InfrastructureMedium
A network engineer is configuring a Cisco router to automatically execute a series of commands if a specific event occurs, such as an interface going down or an SNMP trap being received. The engineer wants to avoid manual intervention for these routine tasks. Which feature should the engineer use?
- ASyslog
- BSNMP
- CIP SLA
- DEEM
Show answer & explanationAnswer & explanation
Correct answer: D. EEM
Embedded Event Manager (EEM) is a powerful and flexible feature in Cisco IOS that allows engineers to define policies to respond to various events on the router. These policies can trigger a series of predefined actions, such as executing CLI commands, sending emails, or generating SNMP traps, thus automating routine tasks.
Why the other options are wrong
- A. Syslog collects log messages, but it does not inherently automate command execution in response to those messages.
- B. SNMP is used for monitoring and managing network devices, but not for automatically executing commands based on events.
- C. IP SLA actively measures network performance, but it's not a general-purpose event automation tool.
Embedded Event Manager (EEM)
A powerful and flexible feature in Cisco IOS that allows network devices to detect events and take automated actions in response, reducing the need for manual intervention.
- Detects various events (interface status, syslog, SNMP, counters).
- Executes predefined actions (CLI commands, Tcl scripts, email).
- Automates routine tasks and responses.
- Enhances network resilience and operational efficiency.
Memory trick: EEM: Event-driven, Execute commands, Master of automation.
