The Troubleshooting BIG-IP LTM v11 course gives networking professionals hands-on knowledge of how to troubleshoot a BIG-IP LTM system using a number of troubleshooting techniques as well as troubleshooting and system tools. This course includes lectures, labs, and discussions. Throughout this course, you will have access to a BIG-IP that uses a typical Internal-External VLAN architecture with a pool of servers (HTTP, HTTPS, SSH, FTP, etc) along with web application servers. In the lab for this module, you will license the BIG-IP, set up the Internal and External VLANs, and create the Pools and Virtual Servers that you will use as part of your troubleshooting exercises.

In addition to the topics above, lab exercises will provide a chance to practice troubleshooting problems using the BIG-IP information, troubleshooting methodology, and tools that you have learned.

This course is meant for BIG-IP administrators, network engineers, applications engineers, etc., who will be responsible for troubleshooting problems associated with their BIG-IP system.

This course assumes that you have successfully completed the Administering BIG-IP course, or equivalent, and have hands-on experience working in a production BIG-IP LTM environment for several months. You should have a solid understanding of the environment in which the BIG-IP is deployed.

• Students should be familiar with the BIG-IP LTM system and, in particular, how to set up and configure a BIG-IP LTM system, including virtual servers, pools, profiles, VLANs and self-IPs.

Students are required to complete one of the following F5 prerequisites before attending this course:

• Administering BIG-IP
• F5 Certified BIG-IP Administrator

In addition, the following web-based courses will be very helpful for any student with limited BIG-IP LTM administration and configuration:

• Getting Started with BIG-IP web-based training
• Getting Started with BIG-IP Local Traffic Manager (LTM) web-based training

Students should understand:

• TMOS administration
• Network concepts and configuration
• Programming concepts
