NDMP data connection types

In a Vserver aware NDMP mode, the supported NDMP data connection types depend on the NDMP control connection LIF type and the status of the CAB extension. This NDMP data connection type indicates whether you can perform a local or a three-way NDMP backup or restore operation.

You can perform a three-way NDMP backup or restore operation over a TCP or TCP/IPv6 network. The following tables show the NDMP data connection types based on the NDMP control connection LIF type and the status of the CAB extension.

NDMP data connection type when CAB extension is not supported by the backup application

NDMP control connection LIF type NDMP data connection type
Node-management LIF LOCAL, TCP, TCP/IPv6
Data LIF TCP, TCP/IPv6
Cluster-management LIF TCP, TCP/IPv6
Intercluster LIF LOCAL, TCP, TCP/IPv6

NDMP data connection type when CAB extension is supported by the backup application

NDMP control connection LIF type NDMP data connection type
Node-management LIF LOCAL, TCP, TCP/IPv6
Data LIF TCP, TCP/IPv6
Cluster-management LIF LOCAL, TCP, TCP/IPv6
Intercluster LIF LOCAL, TCP, TCP/IPv6
Note: In Data ONTAP 8.2, you cannot configure intercluster LIFs with IPv6 addresses. For more information about IPv6 and intercluster LIF, see Clustered Data ONTAP Network Management Guide.
