Troubleshooting BIG-IP v.17.1 [ARR_F5N_BIG-TRBL-INT2]

OVERVIEW

This 2-day course gives network administrators, network operators, and network engineers a functional understanding of the BIG-IP system as it is commonly deployed in an application delivery network. 

The course introduces students to the BIG-IP system, its configuration objects, how it processes traffic, and how typical administrative and operational activities are performed. 

The course includes lecture, hands-on labs, interactive demonstrations, and discussions.

Course Topics

• Configuration Project

• Troubleshooting Methodology

• F5 Support

• Troubleshooting - Bottom to Top

• Troubleshooting Tools

• Using System Logs

OBJECTIVES

At the end of this course, the student will be able to: 

• Describe the role of the BIG-IP system as a full proxy device in an application delivery network

• Set up, start/restart/stop, license, and provision the BIG-IP system

• Create a basic network configuration on the BIG-IP system including VLANs and self IPs

• Use the Configuration utility and TMOS Shell (tmsh) to manage BIG-IP resources and use as a resource when troubleshooting

• Create, restore from, and manage BIG-IP archives

• Understand and implement troubleshooting methodology to find and resolve issues

• View resource status, availability, and statistical information and use this information to determine how the BIG-IP system is currently processing traffic

• Use iApps to update BIG-IP configuration

• Perform troubleshooting and problem determination activities including using the iHealth diagnostic tool, researching known issues and solutions on AskF5, submitting a problem ticket to F5 Technical Support, and view traffic flow using tcpdump

• Understand the tools (ping, netstat, tcpdump, ssldump, WireShark, diff, Kdiff3, Fiddler, BIG-IP logs, etc.) available to use to identify BIG-IP and network issues from bottom to top

• List log files available, understand log levels, and use the appropriate files, log levels, and filters for troubleshooting

• Use High Speed Logging (HSL) and SNMP trap implementations to perform troubleshooting and problem determination activities

• Describe the role of iRules in affecting traffic behavior and how to use them to aid with troubleshooting and problem determination

AUDIENCE

This course is intended for network administrators, operators, and engineers 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.
