NDMP Data Models NDMP Backup topology

3. IMPORTANT INFORMATION WRT LIF & PORT REQUIREMENT:
Whether Node-scoped or SVM-scoped, Intercluster is a preferred NDMP LIF for both control & Data
communication. Ensure NDMP Port 10000 is allowed through firewall policy. However, in cases
where Data LIFs are the only available option presented to Backup Applications, then Data
Connection LIF selection can be very tricky. This is b'cos you cannot hard-code which Data LIF you
want to use. This is purely based on the first available Data LIF in the communicating subnet. In
other words - The order at which the Data interface is used depends on the order in which the
interface appears in the node-run output of 'ifconfig -a'.
