Configuring Port Settings
Using the Web interface, you can configure the
speed/duplex and flow control settings of each port.
You can also view the current connection status of
each port or shut down or disable ports.
Two tabs are available on the Port Configuration
page:
Basic Port Configuration
Advanced Port Configuration
Basic Port Configuration
Use the Basic Port Configuration tab to enable and
disable the port and its flow control settings and to
set the speed/duplex of the port.
The following options are available:
Number – Physical port number
Label – Optional name for the port to help you
identify the device connected to it. For example, if
an access point is connected to this port, you can
label it as
Access Point.
Status – Enables and disables the port
Flow Control – Enables and disables flow control
on the port. When flow control is enabled for the
port, the Switch regulates the packet flow so that
a sending device does not transmit more packets
than a receiving device can process. If flow control
is disabled, packets may be dropped under certain
periods of high traffic.
Flow control is enabled by default.
Speed Duplex – Sets the speed and duplex mode
of the port. Available options include auto, 10
half-duplex, 10 full-duplex, 100-half duplex, and
100 full-duplex. For 1000 Mbps connections, see
Speed/Duplex for 1000 Mbps Connections
below.
Auto (or autonegotiation), which is enabled by
default, sets the optimum combination of speed
and duplex that can be supported by both ends of
the link.
If you modify any of these settings, click Apply to save
your changes.

You cannot preset the speed to 1000Mbps. To run a
port at 1000Mbps, you must enable autonegotiation
for the port. When autonegotiation is enabled, the
