Answer

  • The portmap service maps RPC services to the ports on which they listen.
  • The portmap service was always accessible in ONTAP 9.3 and earlier, became configurable in ONTAP 9.4 through ONTAP 9.6, and is managed automatically starting in ONTAP 9.7.
    • 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.
    • From ONTAP 9.4 through ONTAP 9.6, 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. Instead, the portmap port is opened automatically for all LIFs that support the NFS service.
  • NOTE:
    • Both data-nfs service and management-portmap service provide the same portmap service  tcp/udp:111.
    • data-nfs service is used for data LIF and  management-portmap service is used for management LIF.
