ONTAP port usage on a storage system

A number of well-known ports are reserved for ONTAP communications with specific services. Port conflicts will occur if a port value in your storage network environment is the same as on ONTAP port.

Network Ports​

The following table lists the TCP ports and UDP ports that are used by ONTAP.
