ONTAP 9.14

to Japanese version

Enable the NetBios name service

The NetBios name service (NBNS, sometimes called Windows Internet Name Service or WINS) is disabled by default. Previously, CIFS-enabled storage virtual machines (SVMs) sent name registration broadcasts regardless of whether WINS was enabled on a network. To limit such broadcasts to configurations where NBNS is required, you must enable NBNS explicitly for new CIFS servers.

Before you begin
  • If you are already using NBNS and you upgrade to ONTAP 9, it is not necessary to complete this task. NBNS will continue to work as before.

  • NBNS is enabled over UDP (port 137).

  • NBNS over IPv6 is not supported.

  1. Set the privilege level to advanced.

    set -privilege advanced
  2. Enable NBNS on a CIFS server.

    vserver cifs options  modify -vserver <vserver name> -is-nbns-enabled true
  3. Return to the admin privilege level.

    set -privilege admin
