Applies to

  • ONTAP 9
  • NFSv3
  • Portmapper

Answer

  • In ONTAP 9.3 and earlier, the portmap service rpcbind was always accessible on port 111 in network configurations that relied on the built-in ONTAP firewall rather than a third-party firewall.
  • Starting in ONTAP 9.4, you can modify firewall policies to control whether the portmap service is accessible on particular LIFs.
  • Starting in ONTAP 9.7, the portmap firewall service is eliminated, and the portmap port is opened automatically for all LIFs that support the NFS service.
