(iii) Po r t Trun k ing
Applicable to NAS models with two LAN ports only. This feature is not supported by TS-110, TS-119,
TS-210, TS-219, and TS-219P.
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 both LAN ports of the NAS are connected to the same
switch and you have configured the settings described in sections (i) and (ii).
Follow the steps below to configure port trunking on the NAS:
1. Select the option ‘Enable Network Port Trunking’.
2. Choose a port trunking mode from the drop-down menu. The default option is Active
Backup (Failover).
3. Click ‘Apply’.
