Technical Details

what runs on :11105

NetApp ONTAP uses TCP 11105 for intercluster data transfer. It works alongside TCP 11104, which handles intercluster communication and session management; the data exchanged on 11105 is part of the vendor-specific ONTAP cluster-peering and replication protocol, not a general-purpose file-transfer service. Current ONTAP releases support cluster-peering encryption, which is enabled by default for newly created peer relationships in recent releases; older configurations may differ.

security overview

Intercluster transfers can contain replicated business data, so allow this port only between the intercluster LIFs of trusted clusters, not broadly from the internet. Recent ONTAP peer relationships encrypt intercluster traffic by default, but verify the ONTAP version and peer encryption settings, especially in older environments.
