Troubleshooting BIG-IP®

Apply bottom-to-top techniques to troubleshoot BIG-IP systems. Review a variety of lower layer tools including ping, bigtop, netstat and tcpdump for manipulating different flags for viewing hex and ASCII.

Analyze network protocols using Wireshark and a variety of capture file formats including pcap and tcpdump. Build filters and use different commands and expressions to capture data on different connections in hands-on lab scenarios. Use the Fiddler HTTP proxy to view and analyze different session elements including URL, Content-Type and other headers, bytes sent/received, response codes, and performance statistics. Explore various curl command options for testing endpoint availability and analyzing ingress and egress payloads in detail.

Learn how to use KDiff to compare files from different BIG-IP devices for locating different traffic processing objects. Gain familiarity with using local and remote logging data, facilities, messaging, and levels for troubleshooting. See how iRules can be used for setting up message logging and logging levels. Finally, learn how to create an analytics profile to view traffic statistics, application visibility, and reporting.

This course is intended for network administrators responsible for managing the normal day-to-day operation and administration of a BIG-IP application delivery network. This course presents the prerequisite knowledge for many of F5’s other BIG-IP instructor-led training courses.

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:

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

General network technology knowledge and experience are recommended before attending any F5 Global Training Services instructor-led course, including OSI model encapsulation, routing and switching, Ethernet and ARP, TCP/IP concepts, IP addressing and subnetting, NAT and private IP addressing, NAT and private IP addressing, default gateway, network firewalls, and LAN vs. WAN.

Students should be familiar with and be able to configure basic BIG-IP elements such as virtual servers, pools, pool members, and nodes, pool monitors, and basic virtual server profiles. In addition, students should be familiar with the basics of the Linux command line, and have solid understanding of Layer 2 Ethernet and ARP networking, Layer 3 and 4 TCP/IP networking, including IP addressing and subnetting, Layer 7 HTTP networking, and HTML.

The following course-specific knowledge and experience is suggested before attending this course:
• Web application delivery
• HTTP, HTTPS, FTP and SSH protocols
• TLS/SSL

F5 offers exam blueprints and exam study guides for the certification exams. The F5 Networks training courses serve to further expand and refresh knowledge in this context.

The courses Administering BIG-IP and Troubleshooting BIG-IP® are a useful addition to your preparation for the F5 Certified BIG-IP Administrator exams.
