Description

The 3-day DANZ Monitoring Fabric (DMF) Specialist course will establish sound understanding and technical proficiency required to deploy and operate DMF, a next-generation network packet broker (NPB). The course demonstrates why telemetry, monitoring, and visibility are crucial for your networks. Using extensive practical labs, this course explores how DMF enables pervasive network observability by providing real-time and historical insights into your physical, virtual, and container environments.

Labs

The DMF Specialist course includes diverse practical labs. The labs are accessible for three weeks. One week during the instructor-led course, and two additional weeks to work on labs independently with every student given their own dedicated environment. Students can connect to these cloud-based labs from anywhere at any time.

Lab Activities

Hands-on DMF environment
Configure DMF using CLI and GUI
Configuring Controllers and Switches
Determine status of fabric, controller, and switches
Perform shutdown and bring-up operations
Configuring DMF Policies
Validate traffic at delivery tools
Use trackers to get visibility of production network traffic
Troubleshooting DMF
Monitor traffic utilization within the fabric
Usage of fabric counters and logs for troubleshooting

Target Audience

This course is suitable for engineers with at least mid-level networking experience and are comfortable with basic networking technologies and configurations. The course is best suited for students who are in network monitoring positions, or are looking to progress into these positions.
