Course Overview

This two-day Juniper course provides detailed coverage of virtual LAN (VLAN) operations, Multiple Spanning Tree Protocol (MSTP) and VLAN Spanning Tree Protocol (VSTP), monitoring and troubleshooting tools and features, authentication and access control for Layer 2 networks, IP telephony features, and class of service (CoS) on the EX Series Ethernet Switches.

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


After successfully completing this course, you should be able to:

  • Implement filter-based VLAN assignments.
  • Restrict traffic flow within a VLAN.
  • Manage dynamic VLAN registration.
  • Tunnel Layer 2 traffic through Ethernet networks.
  • Review the purpose and operations of a spanning tree.
  • Implement multiple spanning tree instances in a network.
  • Implement one or more spanning tree instances for a VLAN.
  • Describe a basic troubleshooting method.
  • List common issues that disrupt network operations.
  • Identify tools used in network troubleshooting.
  • Use available tools to resolve network issues.
  • List the benefits of implementing end-user authentication.
  • Explain the operations of various access control features.
  • Configure and monitor various access control features.
  • Describe processing considerations when multiple authentication and access control features are enabled.
  • Describe some common IP telephony deployment scenarios.
  • Describe features that facilitate IP telephony deployments.
  • Configure and monitor features used in IP telephony deployments.
  • Explain the purpose and basic operations of class of service.
  • Describe class of service features used in Layer 2 networks.
  • Configure and monitor class of service in a Layer 2 network.
