This two-day course provides detailed coverage of 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), monitoring and troubleshooting tools and features supported on Juniper Networks® EX Series Switches.
Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos operating system (OS) and monitoring device and protocol operations. This course uses Juniper Networks® EX4300 Switches for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running Junos OS. This course is based on Junos OS Release 21.4R3.
