+        - Check intents
+        - Verify flows
+        - Ping hosts
+        - Reroute
+            - Link down
+            - Verify flows
+            - Check topology
+            - Ping hosts
+            - Link up
+            - Verify flows
+            - Check topology
+            - Ping hosts
+        - Remove intents
+    Required:
+        name - Type of point intent to add eg. IPV4 | VLAN | Dualstack
+        host1 - Name of first host
+        host2 - Name of second host
+    Optional:
+        onosNode - ONOS node to install the intents in main.CLIs[ ]
+                   0 by default so that it will always use the first
+                   ONOS node
+        deviceId1 - ONOS device id of the first switch, the same as the
+                    location of the first host eg. of:0000000000000001/1,
+                    located at device 1 port 1
+        deviceId2 - ONOS device id of the second switch
+        port1 - The port number where the first host is attached
+        port2 - The port number where the second host is attached
+        ethType - Ethernet type eg. IPV4, IPV6
+        mac1 - Mac address of first host
+        mac2 - Mac address of the second host
+        bandwidth - Bandwidth capacity
+        lambdaAlloc - Allocate lambda, defaults to False
+        ipProto - IP protocol
+        ip1 - IP address of first host
+        ip2 - IP address of second host
+        tcp1 - TCP port of first host
+        tcp2 - TCP port of second host
+        sw1 - First switch to bring down & up for rerouting purpose
+        sw2 - Second switch to bring down & up for rerouting purpose
+        expectedLink - Expected link when the switches are down, it should
+                       be two links lower than the links before the two
+                       switches are down
