How to see data transfer on an ONTAP cluster network

ONTAP clusters utilize a backend cluster network to allow multiple HA pairs to communicate and provide more scale for performance and capacity. This is done by allowing you to nondisruptively add new nodes (and, as a result, capacity and compute) into a cluster. Data will be accessible regardless of where you connect in the cluster. …

I like to use Wireshark for Mac and Windows, and regular old tcpdump for Linux. For ONTAP, you can run packet captures …
