Port Management > Link Aggregation

You can create multiple links between devices that work as one virtual, aggregate link. This is known as a Link Aggregrated Group (LAG). LAGs offers a dramatic increase in bandwidth for network segments where bottlenecks exist, as well as providing a fault-tolerant link between two devices. You can create up to eight LAGs on the Switch. Each LAG can contain up to eight ports.

LAG  The LAG number (1-8).

Description  The user-defined description for the LAG.

Admin Status  The administrative status of the interface. To change the status, select Up to enable the interface, or select Down to disable it.

Type  Indicates if a LAG has been manually configured (static) or dynamically set through LACP.

Link Status  Displays the status of the link. Speed  Displays the port speed.

Duplex  Displays the duplex mode. Flow Control  Displays the flow control. LAG Mode  Displays the LAG mode.

Detail  To create a new LAG, click Detail in the Detail column to display the Link Aggregation detail screen.

LAG Configuration

The Link Aggregation detail screen lets you configure a LAG. You can create a LAG, select its ports, enable/disable the LAG, and set the capability advertisements, speed, duplex mode, and flow control. To use this screen, click Detail on the Port Settings screen.
