Developing iRules For BIG-IP - V15.1

CODE: F5N_BIG-IRULE-CFG

LÄNGE: 3 Tage

PREIS: €2.725,00

Beschreibung

This course provides networking professionals a functional understanding of iRules development. The course builds on the foundation of the Administering BIG-IP or Configuring LTM course, demonstrating how to logically plan and write iRules to help monitor and manage common tasks involved with processing traffic on the BIG-IP system. Extensive course labs consist of writing, applying and evaluating the effect of iRules on local traffic. This hands-on course includes lectures, labs, and discussions.

Lernziel

  • Describe the role of iRules in customizing application delivery on a BIG-IP system
  • Describe best practices for using iRules
  • Define event context, and differentiate between client-side and server-side contexts, request and response contexts, and local and remote contexts
  • Trigger an iRule for both client-side and server-side request and response events
  • Assign multiple iRules to a virtual server and control the order in which duplicate events trigger
  • Describe and use a testing methodology for iRule development and troubleshooting
  • Use local variables, static variables, lists, arrays, the session table, and data groups to store information needed for iRule execution
  • Write iRules that are optimized for runtime and administrative efficiency
  • Use control structures to conditionally branch or loop within an iRule
  • Log from an iRule using Linux syslog-ng or TMOS high-speed logging (HSL)
  • Incorporate coding best practices during iRule development
  • Use analyzer tools to capture and view traffic flow on both client-side and server-side contexts
  • Collect and use timing statistics to measure iRule runtime efficiency
  • Write iRules to help mitigate and defend from some common HTTP attacks
  • Differentiate between decimal, octal, hexadecimal, floating-point, and exponential notation
  • Parse and manipulate strings using Tcl commands and iRule functions
  • Write iRules to access and manipulate HTTP header information
  • Write iRules to collect customized statistics
  • Implement universal persistence via an iRule
  • Modify payload content using an iRule with a stream profile

Zielgruppe

This course is intended for system administrators, network administrators and application developers responsible for the customization of traffic flow through a BIG-IP system.

Voraussetzungen

Students must complete one of the following F5 prerequisites before attending this course:

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

 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
  • Ethernet and ARP
  • TCP/IP concepts
  • IP addressing and subnetting
  • NAT and private IP addressing
  • Default gateway
  • Network firewalls
  • LAN vs. WAN

The following course-specific knowledge and experience is suggested before attending this course:

  • HTTP protocol
  • Any programming language

Inhalt

  • Setting up the BIG-IP system
  • Getting started with iRules
  • Leveraging DevCentral resources for iRule development
  • Exploring iRule elements, including events, functions, commands, variables, and operators
  • Using control structures for conditional branching and looping
  • Mastering whitespace, grouping, and special symbols
  • Measuring iRule efficiency using timing statistics
  • Logging from an iRule using syslog-ng and high-speed logging (HSL)
  • Optimizing iRules execution, including implementing efficiency best practices
  • Modularizing iRules for administrative efficiency, including using procedures
  • Securing web applications with iRules, including preventing common HTTP attacks, securing HTTP headers and cookies, and implementing HTTP strict transport security (HSTS)
  • Working with strings, including using Tcl parsing commands and iRules parsing functions
  • Accessing and manipulating HTTP traffic, including applying selective HTTP compression
  • Working with iFiles and data groups
  • Using iRules with universal persistence and stream profiles
  • Gathering statistics using STATS and ISTATS
  • Incorporating advanced variables, including arrays, static variables, and the session table

Major Course Changes since v13
Developing iRules for BIG-IP v14.0 no longer covers the iRules Editor as it is not compatible with BIG-IP v14.0. Discussion of the Rule Profiler feature has been removed from the main course but can be covered as an add-on topic, if desired.
