Overview

This two-day course is designed to provide students with intermediate switching knowledge and configuration examples using Junos Enhanced Layer 2 Software. This course includes an overview of switching concepts and operations, virtual LANs (VLANs), the Rapid Spanning Tree Protocol (RSTP), 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. This course uses Juniper Networks EX4300-24T Series Ethernet Switches for the hands-on components, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on Junos OS Release 21.4R3.

Students will learn:

  • List the benefits of implementing switched LANs.
  • Describe transparent bridging concepts and operations.
  • Describe terms and design considerations for switched LANs.
  • List enterprise platforms that support Layer 2 switching.
  • Configure interfaces for Layer 2 switching operations.
  • Display and interpret the Ethernet switching table.
  • Explain the concept of a VLAN.
  • Describe access and trunk port modes.
  • Configure and monitor VLANs.
  • Describe voice VLAN and native VLAN concepts.
  • Explain inter-VLAN routing operations.
  • Configure and monitor inter-VLAN routing.
  • Explain when a spanning tree is required.
  • Describe STP and Rapid Spanning Tree Protocol (RSTP) operations.
  • List some advantages of using RSTP over STP.
  • Configure and monitor RSTP.
  • Describe the bridge protocol data unit (BPDU), loop, and root protection features.
  • Configure and monitor the BPDU, loop, and root protection features.
  • List and describe various port security features.
