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.
