Specifying NDMP access by host or interface

You can use the options ndmpd.access command to specify the hosts or interfaces through which NDMP sessions are permitted. Conversely, you can also specify hosts or interfaces to block from NDMP sessions.

Steps

  1. Start a console session on the storage system to which you want to restrict NDMP access.
  2. Enter the following command:
    options ndmpd.access {all|legacy|host[!]=hosts|if[!]=interfaces}

    all is the default value, which permits NDMP sessions with any host.

    legacy restores previous values in effect before a Data ONTAP version upgrade.
    Note: In the case of Data ONTAP 6.2, the legacy value is equal to all.

    host=hosts is a parameter string that allows a specified host or a comma-separated list of hosts to run NDMP sessions on this storage system. The hosts can be specified by either the host name or by an IPv4 or IPv6 address.

    host!=hosts is a parameter string that blocks a specified host or a comma-separated list of hosts from running NDMP sessions on this storage system. The hosts can be specified by either the host name or by an IPv4 or IPv6 address.

    if=interfaces is a parameter string that allows NDMP sessions through a specified interface or a comma-separated list of interfaces on this storage system.

    if!=interfaces is a parameter string that blocks NDMP sessions through a specified interface or a comma-separated list of interfaces on this storage system.
