+### Assigning a VLAN to an image
+This example shows how to assign a VLAN to an image.
+
+For this example, we'll use the following values from other tables:
+
+* module.id for handling VLAN config type: 67
+* image.id for the image in this example: 524
+* affiliation.id for the desired affiliation: 6
+* reservation.id for the image: 2748
+* user.id that owns the configs: 54
