Novice Question - irules

This is a quick novice question--does the F5 platform come with irule capability by default? Or does it need to be added, licensed or otherwise enabled first?

    yes, the default comes with iRules. But iRulesLX which is based on Node.js is not enabled by default - it is licensed and provisioned

    kirkpabk, PeteWhite is 100% here, so I marked this solution as correct. One caveat: there is functionality (some commands and events) that is licensed module specific, so those particular features within iRules will not work by default, you have to be licensed for each of those specific modules to unlock them.
