Course Details

This course is designed to provide students with information about troubleshooting SRX Series hardware, Junos software, and more obscure problems like packet loss and latency, IPsec, security zones and policies, other security features, and chassis clustering. Students will gain experience in monitoring and troubleshooting these topics through demonstration as well as hands-on labs. The course exposes students to common troubleshooting commands and tools used to troubleshoot various intermediate to advanced issues.

This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, 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 12.1R5.5.
