3.2.1.1 Configure Network Trunking
Steps to Configure Trunking Function:
NOTE: It is necessary that the network switch supports the type of
trunking mode that will be used. Otherwise, the network connections
may become unstable.
1. In Network  Device Configuration screen, click “Create Trunking”.
2. The Create Trunking Dialog window will be displayed. Configure the necessary
options.
Create Trunking Configuration Options:
Target Device – Shows the network device names that can be included in
Trunking. To select, press the “Ctrl” key and at the same time click the
network device names.
Mode – Select the Trunking Mode that will be used.
Trunking Mode Options:

Fault Tolerance – Active-Backup policy: If the active Ethernet port fails, the
standby Ethernet port will become active. This enhances the availability of access
to the NAS.

Load Balance / Fault Tolerance - XOR policy: Transmit based on source MAC
address XOR with destination MAC address. This selects the same slave for each
destination MAC address. This mode provides load balance and fault tolerance.

Dynamic Link Aggregation - 802.3ad policy: Combines multiple physical
network links into a single logical link for increased performance. Transmits and
receives on all slaves in the active aggregator. Pre-requisite: the network switch
must support IEEE 802.3ad.

Load Balance - ALB (Adaptive Load Balancing) policy: The receive load
balancing is achieved by ARP negotiation and does not require special switch
support.
