Which Network File System (NFS) TCP and NFS UDP ports are used on the storage system?
Applies to
- ONTAP 9
- Data ONTAP 7-Mode
- NFS v3
Answer
- The default ports used by the storage controller are as follows,
ONTAP 9:
111 TCP/UDP portmapper
2049 TCP/UDP nfsd
635 TCP/UDP mountd
4045 TCP/UDP nlockmgr
4046 TCP/UDP status
4049 TCP/UDP rquotad
Data ONTAP 7-Mode:
111 TCP/UDP portmapper
2049 TCP/UDP nfsd
4046 TCP/UDP mountd
4045 TCP/UDP nlockmgr
4047 TCP/UDP status
4049 TCP/UDP rquotad
- It is possible to modify those default ports, therefore to check the currently configured ports on your storage controller please use the following commands,
Data ONTAP 7-Mode:
7dot> options rpc
rpc.mountd.tcp.port 4046
rpc.mountd.udp.port 4046
rpc.nlm.tcp.port 4045
rpc.nlm.udp.port 4045
rpc.nsm.tcp.port 4047
rpc.nsm.udp.port 4047
rpc.pcnfsd.tcp.port 4048
rpc.pcnfsd.udp.port 4048
rpc.rquotad.udp.port 4049
ONTAP 9:
cDot::*> nfs show -vserver NFSsvm -fields rquotad-port ,nlm-port ,nsm-port ,mountd-port
vserver mountd-port nlm-port nsm-port rquotad-port
------- ----------- -------- -------- ------------
NFSsvm 635 4045 4046 4049
cDot::*>
- Alternatively show the ports listening on the node with the following
cdot::> network connection listening show -node <node name>
Vserver Name Interface Name:Local Port Protocol/Service

- These ports list can also be seen from from most unix clients with the command:
rpcinfo -p <storage-controller-IP>
