Is it possible to configure the DPA network ports for load balancing or failover? (4260183)

No, the DPA NICs cannot be used for load balancing or fail over.

NICs would be in an enclave scenario. In this scenario, the TPAM appliance is not in the same network as the target systems. The DPA can act as a bridge to the target devices when TPAM can access the DPA via one of the NICs and the DPA can access the target systems with the other DPA NIC. For example:

TPAM console                                      Target Systems
192.168.1.x ----> eth0 DPA eth1--->  192.168.2.x
