Applicable to NAS models with two or more LAN ports only.
The NAS supports port trunking which combines two Ethernet interfaces into one to increase the
bandwidth and offers load balancing and fault tolerance (also known as failover). Load balancing is a
feature which distributes the workload evenly across two Ethernet interfaces for higher redundancy.
Failover is the capability to switch over to a standby network interface (also known as the slave
interface) when the primary network interface (also known as the master interface) does not
correspond correctly to maintain high availability.
To use port trunking on the NAS, make sure at least two LAN ports of the NAS have been connected to
the same switch and the settings described in sections (i) and (ii) have been configured.
Follow the steps below to configure port trunking on the NAS:
1. Click “Settings”.
2. Select the network interfaces for a trunking group (Ethernet 1+2, Ethernet 3+4, Ethernet 5+6, or
Ethernet 7+8). Choose a port trunking mode from the drop-down menu. The default option is
Active Backup (Failover).
3. Select a port trunking group to use. Click “Apply”.
