D-Link DES-3250TG Standalone Layer 2 Switch
Enter a source port number in the first field and the range of the ports that you want to segment in the second field. For
example, if you enter “5” in the first field and “5-8” in the second field, packets from port 5 will only be forwarded to ports 5
to 8. Packets to port 9, then, will be dropped. Click Apply to let your changes take effect.

Link Aggregation
Link aggregation is used to combine a number of ports together to make a single high-bandwidth data pipeline. The
participating parts are called members of a link aggregation group, with one port designated as the master port of the group.
Since all members of the link aggregation group must be configured to operate in the same manner, the configuration of the
master port is applied to all members of the link aggregation group. Thus, when configuring the ports in a link aggregation
group, you only need to configure the master port.
The DES-3250TG supports link aggregation groups, which may include from two to eight switch ports each, except for a
Gigabit link aggregation group which consists of the two (optional) Gigabit Ethernet ports of the front panel.
Figure 7- 37. Link Aggregation Group
Data transmitted to a specific host (destination address) will always be transmitted over the same port in a link aggregation
group. This allows packets in a data stream to arrive in the same order they were sent. An aggregated link connection can be
made with any other switch that maintains host-to-host data streams over a single link aggregate port. Switches that use a load-
balancing scheme that sends the packets of a host-to-host data stream over multiple link aggregation ports cannot have an
aggregated connection with the DES-3250TG switch.
