About NetBackup master server in a cluster using multiple interfaces
In a cluster environment, all NetBackup master server traffic and communication flow through the network interface that is associated with the virtual name of the master server. With the ANY_CLUSTER_INTERFACE configuration parameter, you can allow communication through any of the interfaces available to the NetBackup master server.
The following figure depicts a scenario where a clustered NetBackup master server has access to two separate networks (168.1 and 192.1). Client computers are attached to both networks and must be backed up. The virtual name for the master server (for example, NBUV168) can only be associated with one of the networks. So all NetBackup communication only occurs over that specific interface. Clients on other interfaces cannot be contacted.
