- The cluster ports are up, and the cluster LIFs are in their home ports.
- No errors or discards are observed on the cluster ports.
- This cluster was recently converted from using a NetApp CN1610 switch to a switchless cluster.
- The cluster ports used here are e4a, e4b, e4c, e4d, e8a, e8b, e8c, e8d, and they are configured in breakout mode.
