+### NTP Global Configuration
 
+These configuration options are used to modify the way that
+ntp binds to the ports on the switch and which port it uses to
+make ntp update requests from.
+
+***NTP VRF***
+
+If this option is set to `default` then ntp will run within the default vrf
+**when the management vrf is enabled**. If the mgmt vrf is enabled and this value is
+not set to default then ntp will run within the mgmt vrf.
+
+This option **has no effect** if the mgmt vrf is not enabled.
+
+```
+{
+"NTP": {
+    "global": {
+        "vrf": "default"
+        }
+    }
+}
+```
+
+
+***NTP Source Port***
+
+This option sets the port which ntp will choose to send time update requests from by.  
+
+NOTE: If a Loopback interface is defined on the switch ntp will choose this by default, so this setting
+is **required** if the switch has a Loopback interface and the ntp peer does not have defined routes
+for that address.
