Can RPC port 111(portmap) be disabled in ONTAP?

Last Updated:


Applies to

  • Data ONTAP operating in 7-Mode
  • Data ONTAP 8
  • ONTAP 9


  • There is currently no way to disable portmapper (port 111) in either Data ONTAP 7-Mode
  • In ONTAP 9.3 and earlier (including Clustered Data ONTAP 8.x), 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.
