1. The active SMP Gateway receives data from the device.
2. The standby SMP Gateway is updated.

the physical IP address.
19.5 Teaming NICs for Network Fault Tolerance
(SMP 16 Only)
All SMP 16 models are equipped with two Network Interface Cards (NICs). You can
group both NICs for network fault tolerance. This process is called NIC Teaming.
The SMP 16’s implementation of NIC Teaming cannot be used for load balancing. Its
sole purpose is for network fault tolerance: if one NIC fails, the network connection does
not cease and continues to operate on the other NIC.
To learn how to configure your SMP 16 for NIC Teaming, refer to the SMP 16 Installation
Guide, under the “Configuring your TCP/IP settings” section.
