Troubleshooting BIG-IP

This course gives networking professionals hands-on knowledge of how to troubleshoot a BIG-IP system using a number of troubleshooting techniques as well as troubleshooting and system tools. This course includes lectures, labs, and discussions.

The goal of this course is 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
  • 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;
    Support, and view traffic flow using tcpdump
  • List log files available, understand log levels, and use the appropriate files, log levels, and filters for troubleshooting
  • Implement High Speed Logging (HSL) and SNMP traps 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
