+====== 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''
