The Variable Manager provides the ability for an activity author to add dynamic capabilities into an activity. These capabilities allow an author to create activities that change each time they are loaded or reset. This capability is enabled by creating pools of values and then creating variables which use the pool values to enable dynamic capabilities. The variables allow you to change many aspects of an activity, including but not limited to, Device names, IP addressing, Routing statements, DHCP and DNS records.↵ ↵ Quick Reference: for a full guide, see the Packet Tracer help files. There are four types of variables that can be created in the Variable Manager. They are identified by the tabs at the top of this page. With the exception of the Seeds, the variables are created using a combination of a resource pool and an associated variable. Each type tab has a place to enter both the pool and the variable information. The seeds tab, due to the simplicity of the type combine both parts into one operation. ↵ ↵ How to create a variable:↵ 1. Fill in the variable Name↵ 2. Select the associated Pool Name (the pool must be already created to show in the dropdown list)↵ 3. Specify the Variable Type (dropdown: Random, Element Position, Seed, Entire Range)↵ 4. Specify the Value (if Element Position is selected a number within the range of values is specified, if seed is selected a seed name is entered for the value)↵ ↵ Variables can select values in one of 4 ways. ↵ Random – Any value in the pool. ↵ Element Position – An integer value that selects the same position from the pool each time. ↵ Seed – A position defined by a Seed variable in the Seed tab. A method for allowing the same position to be used in multiple variable selections. ↵ Entire Range – A variable used in the Activity Wizard answer network to accept any input as correct as long as it is contained in the associated pool.
