This four-day course discusses the configuration of Juniper Networks EX-series switches in a
typical network environment. Key topics include a platform overview, user configuration
interfaces, initial and secondary system configuration tasks, operational monitoring of an
EX-series switch, Ethernet switching concepts, the Spanning Tree Protocol (STP), inter-VLAN
routing, switching security protocols and features, IP telephony features, and design and
implementation considerations. This course is based upon JUNOS software for EX-series
switches Release 9.0R2.
Through demonstrations and hands-on labs, you will gain experience in configuring and
monitoring the EX-series switches.
After successfully completing this course, you should be able to:
• Describe common deployment options for the EX-series switches.
• Perform operational monitoring tasks typically associated with EX-series switches.
• Install and configure an EX-series switch in a network.
• Form a Virtual Chassis system by connecting multiple EX-4200 switches.
•Configure and monitor virtual LANs (VLANs).
• Create a loop-free network environment using STP.
• Implement inter-VLAN routing using static and dynamic methods.
• Define and apply routing policy and firewall filters.
• Secure a switch port using available port access security features.
• Configure and monitor IP telephony features such as Power over Ethernet (PoE),
voice VLAN, and the Link Layer Discovery Protocol (LLDP).
• Design and implement a Layer 2 network using EX-series switches.
