Junos Enterprise Switching (JEX)

The 2-day Junos Enterprise Switching course that provides students with intermediate switching knowledge and configuration examplesThis 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.

Students will gain experience in configuring and monitoring the Junos operating system and in monitoring device operationsThis course uses Juniper Networks EX-4200 Series Ethernet Switches for the hands-on component.
