Enabling NFS Protocol Support
To enable NFS access to the system, enter an NFS license key on the License Keys page in the NAS Manager.
Supported clients and protocols
The server supports all clients compliant with NFS version 2, version 3, or version 4 standards. NFS versions 2, 3 and 4 are supported over TCP. The following table summarizes the supported versions of NFS and other UNIX protocols:
| Protocol | Supported versions |
| NFS | 2, 3, and 4 |
| Port Mapper | 2 |
| Mount | 1 and 3 |
| Network Lock Manager (NLM) | 1, 3, and 4 |
| Network Status Monitor (NSM) | 1 |
CautionWhile it is possible to use UDP with NFS on versions 2 and 3, it is not recommended due to inherent risks. On the
NAS server, UDP is not automatically presented as a transport option for the NFS service by the Port Mapper service. To register NFS over UDP in the Port Mapper service, see the
rpc-service-nfs-udp command.
