I now use this with a TP-Link managed switch and the DS1520+.Īs I've vSwitch enabled I haven't tried Balance XOR, which sounds like static LAG and may be supported by my Easy Smart switch, and I've not considered using active/backup LAG. But this does require you to setup the dynamic LAG on the switch. If you have a managed switch that supports IEEE 802.3ad / 802.1AX then you have more options: IEEE 802.3ad Dynamic Link Aggregation and Balance-TCP. I used to do this with with a TP-Link Easy Smart 8-port switch and my DS1520+. It works well and there's zero switch configuration (even if you do use a managed switch). If you have an unmanaged switch then your options are limited to either Adaptive Load Balancing or Balance-SLB. You can choose this mode without configuring the switch. When the active network interface malfunctions, the other one will take over to maintain the network connectivity. Active/Backup Mode: This mode provides your Synology NAS with network fault tolerance using two network interfaces.If multiple switches are used, they must be stackable and properly configured. Balance-TCP: This mode enables the connection with the switches configured as Dynamic Link Aggregation (IEEE 802.3ad LACP).Balance-SLB: This mode balances the network traffic without requiring the support for specific network switches and enables the connection between two switches.You can choose this mode without configuring the switch or with a switch that supports IEEE 802.3ad Link Aggregation. That is, when the active network interface goes down, one of the other LAN ports will take over to maintain the network connection. Active/Standby: This mode provides your Synology NAS with network fault tolerance.With this mode, the lost links can be detected but not the cause (e.g., when the Ethernet cables are unplugged or the switch is wrongly configured). If Link Aggregation is not supported by the switch, the traffic sent by your Synology NAS can still be balanced. If multiple switches are used, these switches have to be stackable and properly configured. Balance XOR: This mode balances the network traffic received and sent by your Synology NAS, and requires Static Link Aggregation to be enabled on the switches.IEEE 802.3ad Dynamic Link Aggregation: This mode optimizes the network traffic received and sent by your Synology NAS, and requires IEEE 802.3ad (Dynamic) Link Aggregation (LACP, 802.1AX) to be enabled on the switches.To avoid unexpected errors, please do not enable Link Aggregation on the switch even when it is supported. Adaptive Load Balancing: This mode optimizes the network traffic received and sent by your Synology NAS whether or not the switch supports Link Aggregation.
