For DiskStations with multiple LAN ports, you can combine multiple LAN interfaces into the Bond [number]
interface with Link Aggregation1
. You can configure this interface as you would with any LAN interface.
To combine multiple LAN interfaces with Link Aggregation:
1 Click Create.
2 Choose any of the following modes and click Next:
Note: Before you enable Link Aggregation, please make sure all LAN cables are connected to the same switch.
IEEE 802.3ad Dynamic Link Aggregation: IEEE 802.3ad is the standard for most Link Aggregation
implementations. A switch with 802.3ad support is required to use in this mode.
Network Fault Tolerance only: If the LAN 1 port becomes unavailable, the system will use LAN 2 to
provide service. You can select this option if your switch does not support IEEE 802.3ad.
3 Select two or more LAN interfaces that will be used for Link Aggregation, and click Next.
4 Configure the network settings and click Apply.
To separate the Bond interface into multiple LAN interfaces:
1 Click the Bond [number] interface on the left side.
2 Click Remove and then click OK.
Term Explanation
Link Aggregation: For DiskStation with multiple LAN ports, you can set your DiskStation to connect multiple
LAN cables to the network at the same time, or assign it with two IP addresses under different subnets. With
Link Aggregation enabled, trunking (combining network bandwidth of aggregated LAN interfaces for multiplied
connection speed) and network fault tolerances (maintaining network connection when any of the aggregated
LAN interfaces is unavailable) are supported.
---------
1 Link Aggregation is only supported on DiskStations with multiple LAN ports.
