Item Description
Port description
Optional description for the port. A maximum of 80 characters can be provided. No special
characters or spaces are allowed.
Port speed
10M: Forces a connection to be made at 10 Mbps.
100M: Forces a connection to be made at 100 Mbps.
1000M: Forces a connection to be made at 1000 Mbps.
Auto: The switch and connected device negotiate the best possible connection speed.
Flow control
IEEE 802.3x ow control is the process of managing the rate of data transmission between
two nodes (i.e., the switch and a connected network client) to prevent a fast sender from
overwhelming a slow receiver. It provides a mechanism for the receiver to control the
transmission speed, so that the receiving node is not overwhelmed with data from the
transmitting node. That sounds like it is a good thing, and it is. So why is the option by default
set to “disabled”? The short answer is because you normally don’t need it and because it can,
in very rare instances, have a negative impact on the overall performance in your network. The
TCP protocol already provides its own ow control mechanism, allowing a sender to throttle
back the speed if the receiver is having problems keeping up.
Port status
ON: Activates the port.
OFF: Disables the port. No connections to it can be made.
Working mode
This parameter controls the duplex mode. In a full-duplex system, both parties can
communicate to the other simultaneously. An example of a full-duplex device is a telephone;
the parties at both ends of a call can speak and be heard by the other party simultaneously.
In networking terms, full duplex allows receiving and transmitting of data at the same time,
whereas half duplex does not. If the telephone is an example for full duplex, then a push-to-
talk CB radio or “walkie-talkie” represents half duplex. The switch can either receive or send
data, but it can never happen simultaneously. Unless you have a specic reason not to do so,
this should be left in “Auto” mode.
Cross line order
Auto MDI-X automatically detects the required cable-connection type and congures the
connection appropriately, removing the need for crossover cables to interconnect switches
or for connecting PCs peer-to-peer. As long as it is enabled on either end of a link, either type
of cable can be used. For auto MDI-X to operate correctly, the data rate on the interface and
duplex setting must be set to “auto.” When two auto MDI-X ports are connected together, which
is normal for modern products, the algorithm resolution time is typically < 500 ms. However, a
~1.4 second asynchronous timer is used to resolve the extremely rare case (with a probability
of less than 1 in 5×1021) of a loop where each end keeps switching. If you don’t understand
any of this, simply leave this value on “Auto.”
