Course Overview
This Instructor Led course is designed to instruct the learner on various topics related to the theory, configuration, and troubleshooting of layer 2 and layer 3 protocols typically found in a Campus networking environment. The theory learned in lecture will be put to practical application with hands-on labs utilizing Dell EMC N-Series switches.
Who should attend
This course is intended for professionals those who configure, manage, and troubleshoot Dell EMC Campus Networking Products.
