| CASE2: Assign devices to controllers |
| CASE21: Assign mastership to controllers |
| CASE3: Assign intents |
| CASE4: Ping across added host intents |
| CASE5: Reading state of ONOS |
| CASE6: Swap nodes |
| CASE7: Check state after control plane failure |
| 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: Install Distributed Primitives app |
| CASE17: Check for basic functionality with distributed primitives |
