Teaming Mode

Select how to use the NSA’s two Gigabit Ethernet interfaces. 
Stand Alone: Select this option to use a separate IP address on each of the two 
Gigabit Ethernet interfaces.
Fault Tolerance: Select this option to use the LAN2 Gigabit Ethernet interface as 
a fail-over (backup) for the LAN1 Gigabit Ethernet interface. Both Gigabit 
Ethernet interfaces are connected to the same subnet. There is one IP address. If 
LAN1 loses its connection, LAN2 takes over the IP address and traffic.
Load Balancing: Select this option to use both Gigabit Ethernet interfaces on the 
same subnet with the same IP address. The NSA distributes the traffic load 
across both interfaces.
Link Aggregation: Select this option to use IEEE 802.3ad port link aggregation 
to combine the two Gigabit Ethernet interfaces into a single logical link. Connect 
both Gigabit Ethernet interfaces to the same device. The peer device must also 
have IEEE 802.3ad port link aggregation enabled for the two interfaces 
connected to the NSA. Both interfaces use the same IP address. If one interface 
loses its connection, the NSA continues to use the other interface.

LAN

Use this section to configure the NSA’s IP address or IP addresses (configure 
LAN1 and LAN2 separately when the Teaming Mode is set to Stand Alone).

Dynamic

Select the Dynamic checkbox to have a DHCP server automatically assign an IP 
address to your NSA. If none is assigned, then the NSA reverts to the default IP 
address of 192.168.1.3.
