5-Port and 8-Port 10/100/1000 Gigabit Smart Switches with PD and AC Power
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 half-duplex operation.
10 Full Supports 10 Mbps full-duplex operation.
100 Half Supports 100 Mbps half-duplex operation.
100 Full Supports 100 Mbps full-duplex operation.
1000 Full Supports 1000 Mbps full-duplex operation.
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
fault-tolerant link between two devices. You can create up
to two LAGs on the Switch. Each LAG can contain up to
five/eight ports.
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.
