Mount an NFS File System by Using an NFS URL
You can choose to include the public
option with an NFS URL. Without the public
option, the MOUNT protocol is used if the public file handle is not supported by the server. The public
option forces the use of the public file handle, and the mount fails if the public file handle is not supported.
Note:
The NFS protocol version that is used when you mount the file system is the highest version supported by both the client and the server. However, you can use thevers=#
option to select a specific NFS protocol version.
