Kurz seznámí účastníky s řadou technik, pomocí kterých lze řešit problémy vznikající při provozu systému BIG-IP, pomocí systémových nástrojů. Tento kurz zahrnuje přednášky, laby a diskuse.

Během tohoto kurzu budete mít přístup k prostředí využívající BIG-IP, s typickou architekturou Internal-External VLAN s backend servery (server HTTP, HTTPS, SSH, FTP atd.). V rámci cvičení budete licensovat BIG-IP, nastavovat VLANy a vytvářet Pooly, virtualní Servery, a odstraňovat problémy.

Budete mít příležitost procvičit si odstraňování a řešení problémů pomocí BIG-IP metodiky  a nástrojů, které jste se naučili.

S ohledem na pokročilý obsah školení důrazně doporučujeme předchozí absolvování kurzu „F5 LTM Configuring“, nebo znalost pokročilé konfigurace F5 modulu LTM (např. globální SNAT, Forwarding VS, Transparentní VS, a jiné)

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 environment for several months.

You should have a solid understanding of the environment in which the BIG-IP is deployed.

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.

Students must complete one of the following F5 prerequisites before attending this course:
•Administering BIG-IP instructor-led course
•F5 Certified BIG-IP Administrator

The following free web-based training courses, although optional, will be very helpful for any student with limited BIG-IP administration and configuration experience.

These courses are available at F5 University(http://university.f5.com):
• Getting Started with BIG-IP web-based training
• Getting Started with BIG-IP Local Traffic Manager (LTM) web-based training

The following general network technology knowledge and experience are recommended before attending any F5 Global Training Services instructor-led course:
• OSI model encapsulation
• Routing and switching
