Packet captures (PCAPs) of traffic between client and cluster can be filtered and analyzed by tools such as Wireshark to ensure that requests, authentication, and transmission are occurring as expected across the desired NICs.
Gathering PCAPs is best performed on the Linux client-side and on the multiple specified interfaces if the client is using the ‘--localports’ NFS mount option.
