====== Tips & Tricks ======
This document is meant to group some examples, tricks and usage tips. 

===== Templates =====

==== Variable inside a relation ====
Need to find variables belonging to another from a port template. 

A template example, using the //Bandwidth_up// value of the port-channel on the physical interface. Using the known //<Chan_id>// variable inside the relation: //PortChannels//
<code>service-policy output PM-<Bandwidth_up@PortChannels:Chan_id=<Chan_id>></code>

===== Scenarios =====

==== Modify context variable ====
In this example the node_class name is modified using the __Replace__ function. This is done using a regular expression.

<code><type> := [Replace(<node_class>, '_.*', '')]</code>
Everything after the first _ (including the _) is removed and the value is assigned to the variable //type//

eg. Before: ''WAN_env_CPE'', after: ''WAN''
