Technical Details

what runs on :11104

NetApp ONTAP uses TCP 11104 for intercluster management traffic. It works with TCP 11105, which carries intercluster data transfer, including SnapMirror replication data. These ports are normally allowed between the cluster intercluster interfaces rather than exposed as general-purpose services. ONTAP versions and configuration affect encryption: modern cluster peering can encrypt intercluster communication, but do not assume every deployment or peer relationship uses encryption.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

security overview

Restrict access to trusted intercluster interfaces and peer clusters; this is not a service that should be exposed to the public internet. An exposed listener can invite probing of ONTAP intercluster services and increase risk to storage replication and cluster operations. Encryption and authentication depend on ONTAP version and peer configuration, so verify them rather than relying on the port number alone.
