+This test verifies control plane resilience from a CLUSTER restart
+
+It consists of 
+
+1) Configure and Install ONOS
+2) Start Mininet and check flow state
+3) Pingall
+4) Induce a CLUSTER restart
+5) check flow state
+6) Pingall
+
+Requirements
+
+ - An updated version of the CPQD switch has to be running to make sure it supports group chaining.
+
+The test is executed using the netcfg subsystem:
+    1) APPS=openflow-base,netcfghostprovider,netcfglinksprovider
+
+The test runs for different topologies:
+ - 2x2 Leaf-Spine and 3-node ONOS cluster
+ - 4x4 Leaf-Spine and 3-node ONOS cluster
+ - Single switch and 3-node ONOS cluster
