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.
