You must identify the LIFs that will be used for establishing a data connection between the data and tape resources, and for control connection between the admin SVM and the backup application. After identifying the LIFs, you must verify that firewall and failover policies are set for the LIFs, and specify the preferred interface role.

Beginning with ONTAP 9.10.1, firewall policies are deprecated and wholly replaced with LIF service policies. For more information, see LIFs and service policies in ONTAP 9.7 and later.

Steps

Identify the intercluster, cluster-management, and node-management LIFs by using the network interface show command with the -role parameter.

The following command displays the intercluster LIFs:

cluster1::> network interface show -role intercluster

            Logical           Status     Network            Current       Current Is
Vserver     Interface         Admin/Oper Address/Mask       Node          Port    Home
----------- ----------        ---------- ------------------ ------------- ------- ----
cluster1    IC1               up/up      192.0.2.65/24      cluster1-1    e0a     true
cluster1    IC2               up/up      192.0.2.68/24      cluster1-2    e0b     true

The following command displays the cluster-management LIF:

cluster1::> network interface show -role cluster-mgmt

            Logical           Status     Network            Current       Current Is
Vserver     Interface         Admin/Oper Address/Mask       Node          Port    Home
----------- ----------        ---------- ------------------ ------------- ------- ----
cluster1    cluster_mgmt      up/up      192.0.2.60/24      cluster1-2    e0M     true

The following command displays the node-management LIFs:

cluster1::> network interface show -role node-mgmt

            Logical           Status     Network            Current       Current Is
Vserver     Interface         Admin/Oper Address/Mask       Node          Port    Home
----------- ----------        ---------- ------------------ ------------  ------  ------
cluster1    cluster1-1_mgmt1  up/up      192.0.2.69/24      cluster1-1    e0M     true
            cluster1-2_mgmt1  up/up      192.0.2.70/24      cluster1-2    e0M     true

Ensure that the firewall policy is enabled for NDMP on the intercluster, cluster-management (cluster-mgmt), and node-management (node-mgmt) LIFs:

Verify that the firewall policy is enabled for NDMP by using the system services firewall policy show command.

The following command displays the firewall policy for the cluster-management LIF:

cluster1::> system services firewall policy show -policy cluster

Vserver     Policy       Service    Allowed
-------     ------------ ---------- -----------------
cluster     cluster      dns        0.0.0.0/0

                        ** ndmp       0.0.0.0/0**

                         snmp       0.0.0.0/0
                         ssh        0.0.0.0/0
                         telnet     0.0.0.0/0
10 entries were displayed.

The following command displays the firewall policy for the intercluster LIF:

cluster1::> system services firewall policy show -policy intercluster

Vserver     Policy       Service    Allowed
-------     ------------ ---------- -------------------
cluster1    intercluster dns        -
                         http       -
                         https      -
                         **ndmp       0.0.0.0/0, ::/0**

                         ssh        -
                         telnet     -
9 entries were displayed.

The following command displays the firewall policy for the node-management LIF:

cluster1::> system services firewall policy show -policy mgmt

Vserver     Policy       Service    Allowed
-------     ------------ ---------- -------------------
cluster1-1  mgmt         dns        0.0.0.0/0, ::/0

                         https      0.0.0.0/0, ::/0
                         **ndmp       0.0.0.0/0, ::/0**
                         ndmps      0.0.0.0/0, ::/0
                         ntp        0.0.0.0/0, ::/0
                         rsh        -
                         snmp       0.0.0.0/0, ::/0
                         ssh        0.0.0.0/0, ::/0
                         telnet     -
10 entries were displayed.

If the firewall policy is not enabled, enable the firewall policy by using the system services firewall policy modify command with the -service parameter.

The following command enables firewall policy for the intercluster LIF:
```
cluster1::> system services firewall policy modify -vserver cluster1 -policy intercluster -service ndmp 0.0.0.0/0
```

Ensure that the failover policy is set appropriately for all the LIFs:

Verify that the failover policy for the cluster-management LIF is set to broadcast-domain-wide, and the policy for the intercluster and node-management LIFs is set to local-only by using the network interface show -failover command.

The following command displays the failover policy for the cluster-management, intercluster, and node-management LIFs:

cluster1::> network interface show -failover

           Logical            Home              Failover              Failover

                                                     ......

If the failover policies are not set appropriately, modify the failover policy by using the network interface modify command with the -failover-policy parameter.
```
cluster1::> network interface modify -vserver cluster1 -lif IC1 -failover-policy local-only
```

Specify the LIFs that are required for data connection by using the vserver services ndmp modify command with the preferred-interface-role parameter.
```
cluster1::> vserver services ndmp modify -vserver cluster1 -preferred-interface-role intercluster,cluster-mgmt,node-mgmt
```

Verify that the preferred interface role is set for the cluster by using the vserver services ndmp show command.

cluster1::> vserver services ndmp show -vserver cluster1

                             Vserver: cluster1
