This article describes Link Aggregation and how to implement it on Datto Switches.
- Datto Switches
Link Aggregation is the process of combining multiple physical links (ports in the case of switches) to form one logical link, for purposes of increasing total available bandwidth, performance and reliability. Link aggregation is most commonly used to link bandwidth intensive devices to the backbone of a network or for connecting core switches with distribution switches, to extend the reach of a network.
Navigating to link aggregation settings
1. In the navigation menu, click Switches, then select Port Settings from the drop-down menu.
To create a Link Aggregate Group (LAG), follow these steps:
1. Select two or more ports, then click the Aggregate button.
2. A prompt asking "are you sure you wish to aggregate these ports together" will display. Click OK to continue.
The ports will then merge and display the ports within the LAG, and that they are now in a Group.
You can split one or more ports from an existing Link Aggregated Group. To do so, follow these steps:
1. Select a LAG.
2. The Split Grouped Ports window will display. Select the ports you wish to remove from the group, then click OK.
- PoE will automatically disable for all ports within the LAG.
- The LAG will use the port settings of the lowest number port.
- Rate limiting is not supported on aggregated ports.
- Link Aggregation requires devices that support the Link Aggregation Control Protocol (LACP; 802.3ad).
