Junos Enterprise Switching

Course Overview

Junos Enterprise Switching (JEX) is a two-day course that provides students with introductory switching knowledge and configuration examples. This course includes an overview of switching concepts and operations, virtual LANs, spanning tree protocol, port and device security features, and high-availability features. This course is based on Junos version 10.1R2.8.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring device operations.
