Junos Enterprise Switching (JEX)

Overview

Junos Enterprise Switching 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 (VLANs), the Spanning Tree Protocol (STP), port and device security features, and high availability (HA) features.

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

Prerequisites

• Students should have basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) reference model and the TCP/IP protocol suite.
• Students should also attend the 'Introduction to the Junos Operating System' (IJOS) and the 'Junos Routing Essentials' (JRE) courses prior to attending this

Participants

• This course benefits individuals responsible for configuring and monitoring EX Series switches.
