3.3.8. Links and variables

There are two options to refer to components involved in network configurations.

  • Create links.

  • Use variables.

If links are used, IP addresses can be entered manually or select the link target from a drop-down menu. Using links has the advantage that future changes in the network setup do not influence the operability of the connection.

Delete the existing links with the Unlink and Unlink as value options.

  • Unlink removes the link connection, 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.

Components can be referenced with the help of variables. By using variables values appearing in several places can be changed at once. If a variable is modified, 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:

$autobind-ip$
