Be sure to click Save Settings and reboot the Switch by going to Admin > Reboot.
Port > Port Settings
You can manually configure the speed, duplex, and flow control settings used on specific ports, or use autonegotiation to allow the Switch to autodetect the connection settings used by the attached device. Full‑duplex mode should be used on ports whenever possible to double the throughput of Switch connections. Flow control should also be enabled to control network traffic during periods of congestion and prevent the loss of packets when port buffer thresholds are exceeded. The Switch supports flow control based on the IEEE 802.3x standard.
Ports > Port Settings
Port Displays the port number.
Link Status Displays the link status of the port.
Mode The current speed and duplex mode settings are displayed here. Auto Speed is enabled by default to allow the Switch to autonegotiate the speed and duplex settings. The following capabilities are supported:
•Auto Speed This option enables autonegotiation. When autonegotiation is enabled, you do not need to specify the capabilities to be advertised.
•10 Half Supports 10 Mbps
•10 Full Supports 10 Mbps
•100 Half Supports 100 Mbps
•100 Full Supports 100 Mbps
•1000 Full Supports 1000 Mbps
•Disabled Disables the port.
Flow Control Indicates whether flow control is enabled or not.
LAG Indicates whether the port is a LAG member.
Enable Jumbo Frames Selecting this enables Jumbo Frame support (up to 9KB).

Port > Static Link Aggregation
You can create multiple links between devices that work as one virtual, aggregate link (LAG). An aggregated link offers a dramatic increase in bandwidth for network segments where bottlenecks exist, as well as providing a
Port > Link Aggregation
LAG Displays the LAG number. By selecting the Port numbers, the port can be added to the LAG group.
Click Save Settings to save any changes.
Port > LACP Settings
Ports can be statically grouped into an aggregate link (that is, LAG) to increase the bandwidth of a network connection or to ensure fault recovery. Or you can use the Link Aggregation Control Protocol (LACP) to automatically negotiate a LAG link between the Switch and another network device. For dynamic LAGs, the switches have to comply with LACP. This Switch supports up to two LAGs. For example, a LAG consisting of two 1000 Mbps ports can support an aggregate bandwidth of 4 Gbps when operating at full duplex.
To avoid creating a loop in the network, be sure you enable LACP before connecting the ports, and also disconnect the ports before disabling LACP.
NOTE: LAG port members will have to be configured with the same speed and duplex mode. A user must ensure the LAG member’s ports have the same speed and duplex settings before activating an LACP group.
