| Description: This test is to determine how ONOS behaves in a control network |
| partion. ONOS 1,2,3 will be split into a sub cluster and ONOS |
| 4,5,6,7 will be in another sub-cluster. |
| |
| List of test cases: |
| CASE1: Compile ONOS and push it to the test machines |
| CASE2: Assign mastership to controllers |
| CASE3: Assign intents |
| CASE4: Ping across added host intents |
| CASE5: Reading state of ONOS |
| CASE6: The Failure case. We will create IPTables rules here. |
| CASE7: Check state after control plane partition. |
| CASE8: Compare topo |
| CASE9: Link s3-s28 down |
| CASE10: Link s3-s28 up |
| CASE11: Switch down |
| CASE12: Switch up |
| CASE13: Clean up |
| CASE14: start election app on all onos nodes |
| CASE15: Check that Leadership Election is still functional |
| CASE16: Repair network partition |
