3.3.8. Links and variables

You have two options to refer to components involved in network configurations.

  • Create links

  • Use variables

If you use links, you can manually enter IP addresses or select the link target from a drop-down menu. Using links has the advantage that future changes in the network setup does not influence the operability of the connection.

You can delete the existing links with the Unlink and Unlink as value options.

  • Unlink ceases the link connection totally, meaning that the link field is left empty.

  • Unlink as value deletes the link but leaves the target IP address in the field which will then behave as a manually added address.

You can refer to components with variables. By using variables you change values appearing in several places at once. If you modify a variable, all corresponding values are changed. Variables are denoted with $ characters preceding and following their names.

Example 3.1. Referring to components with variables

The following is an example for a variable:
