Description
Developing iRules for BIG-IPTo get the most out of this course, you should have a basic understanding of the BIG-IP system. BIG-IP Administration course is Mandatory Pre-Requisites for this course This course will teach you how to develop and manage iRules on the BIG-IP platform. iRules are small, self-contained programs that can be used to customize the behavior of the BIG-IP system. They can be used to perform a variety of tasks, such as:Logging trafficModifying headersGenerating responsesRedirecting trafficControlling accessAnd much moreThe course will cover the following topics:Introduction to iRulesThe Tool Command Language (Tcl)Control structures (IF, Switch)Loop structures (For, Foreach, While)iRule syntax and semanticsCommon iRule events, functions, and variablesTCP/IP events and commandsLoad balancing events and commandsHTTP events and commandsError handling and debuggingTraffic redirection with iRulesBest practices for developing iRulesiRule prioritiesData groupsBy the end of this course, you will be able to:Develop iRules to customize the behavior of your BIG-IP systemManage iRules using the BIG-IP GUI and CLITroubleshoot iRule problemsApply best practices for developing iRulesApply real-world examples of iRules to your own environmentThis course is designed for system administrators and network engineers who want to learn how to use iRules to customize the behavior of the BIG-IP system.In addition to the topics listed above, the course will also cover the following:How to use iRules to monitor trafficHow to use iRules to control accessHow to use iRules to optimize performanceHow to use iRules to troubleshoot problemsThe course will also include a number of real-world examples of how iRules can be used. These examples will help you understand how iRules can be used to solve specific problems.
