5SAVING THE CONFIGURATION
The Intellinet 48‐Port Gigabit Ethernet Web‐Managed Switch provides a myriad of configuration options, many
of which are designed for experienced network administrators and aren’t easy to configure. It would be a real
shame if all the configuration data was lost after a power failure or after the switch was restarted. In order to
make the configuration permanent, it needs to be saved.
Here is how:
If you do not perform this function, you risk losing all the settings after the switch restarts.

6.3 PORT SETTINGS
6.3.1 Basic Config
Access the parameters related to each of the 18 ports. The screen is divided into two sections. The upper
section displays an image of the 18 ports of the Intellinet switch. In order to make changes to a port, simply
click to select it.
Create a selection of multiple ports at once:
Once one port or multiple ports are selected, make changes to the port settings.
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: Force a connection to be made at 10 Mbps.
100M: Force a connection to be made at 100 Mbps.
1000M: Force 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 flow 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 flow
control mechanism, allowing a sender to throttle back the speed if the receiver is
having problems keeping up.
Port status
ON: Activate the port.
OFF: Disables the port. No connections to it can be made.

Item
Description
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 specific 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 configures
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‐Xto 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.”
The screen also shows a table that lists all 18 ports along with their parameters. The “mega frame” value refers
to jumbo frames, which are Ethernet frames with more than 1500 bytes of payload. Define the size of the
jumbo frames in the section SYSTEM ‐>SYSTEM CONFIG.
Clicking the pencil allows editing the port settings, exactly the same way as directly selecting the
port(s) as shown on the previous page.

6.3.2 Port Aggregation
Port aggregation is a method of using multiple Ethernet ports in parallel to increase throughput beyond what a
single connection could sustain and to provide redundancy in case one of the links should fail. As this is
essentially a grouping of ports into one logical unit, we call them Link Aggregation Groups, or “LAG” for short.
This page is used to set up LAGs. Create up to eight different LAGs; each can have up to eight member ports.
Each LAG can be given a custom name, and you must select the ports for the LAG. The example below shows
an LAG group set up with four member ports.

6.3.3 Port Mirroring
Port mirroring is the ability of a
network switch to send a copy of
network packets seen on a switch
port or ports to a network‐
monitoring device connected to
another switch port (i.e., a
computer equipped with a packet
sniffer utility). The Intellinet 48‐
Port Gigabit Ethernet Web‐
Managed Switch provides up to
four groups for port‐mirroring
settings.
The example below shows setting up one mirror group where all traffic occurring on port 1 is being mirrored
to port 16.
