+# Following table view will let you get configuration data about interfaces from a Juniper Switch.
+# For a given interface it will let you query 
+#  - if mode is trunk or access
+#  - What is its native vlan
+#  - What vlans are members of its configuration
+#  - Whether it is enabled or disabled
+#  - What are its logical interfaces.
+#  More can be added as necessary.
