Advanced Junos Enterprise Switching (AJEX)

This two-day course provides detailed coverage of virtual LAN (VLAN) operations, Multiple Spanning Tree Protocol (MSTP) and VLAN Spanning Tree Protocol (VSTP), authentication and access control for Layer 2 networks, IP telephony features, class of service (CoS) and monitoring and troubleshooting tools and features supported on the EX Series Ethernet Switches. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos operating system and in monitoring device and protocol operations.

Target audience:
This course benefits individuals responsible for configuring and monitoring EX Series switches.

AJEX is an advanced-level course. 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 Software Operating System" (IJOS), the "Junos Routing Essentials" (JRE), and the "Junos Enterprise Switching" (JEX) courses prior to attending this class.

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.
  • 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 CoS.
  • Describe CoS features used in Layer 2 networks.
  • Configure and monitor CoS in a Layer 2 network .
  • 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.
