We’ve had the ability to determine which clients are accessing IP addresses in a cluster (network connections active show), as well as CIFS/SMB session information (cifs session show), but could never get granular information about NFS.
The use cases are varied, but usually fall into: 1) Need to discover who’s using a volume before performing migrations, cutovers, etc. 2) Troubleshooting issues 3) Load distribution
Check if any of the physical ports in a LACP are saturated. It is normal on big envs that incorrect load balancing due to the nature of the LB implemented by ONTAP happens if you do not pay attention to the IPs involved in the communication
