Applies to

  • ONTAP 9
  • Intercluster SnapMirror
  • SVM-DR

Answer

The firewall and intercluster firewall policy must allow:

  • TCP ports 11104 and 11105, bidirectionally

Note: ONTAP uses port 11104 to manage intercluster communication sessions, and port 11105 to transfer data.

  • (Optional) TCP port 10000 between Active IQ Unified Manager and the storage system, for some snapshot restores
  • (Optional) TCP port 443 (HTTPS) bidirectionally between the intercluster LIFs, for managing ONTAP arrays using System Manager, or REST APIs
