ONTAP 8.3.2 Defaults – NFS Server

In the 3rd of the ONTAP 8.3.2 defaults series, we look at NFS Server defaults. There are a lot of modify-able NFS server settings (especially since I’m including advanced and diag level settings for completeness), this is not complexity though - since in most cases the settings will be mostly perfectly fine set to defaults - it’s configurability/flexibility/enablement/power for if/when you need to set things differently to default.

All the information presented in the table below can be got from::>


set diag
man nfs server modify
