DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch

Traffic Segmentation

Traffic segmentation is used to limit traffic flow from a single or group of ports, to a group of ports. This method of segmenting
the flow of traffic is similar to using VLANs to limit traffic, but is more restrictive. It provides a method of directing traffic that
does not increase the overhead of the Master switch CPU.
Open the L2 Features folder and click Traffic Segmentation, to view the window shown below.
Figure 7- 17. Traffic Segmentation window
To configure traffic segmentation on the Switch, first specify the Source Port(s) using the From and To drop-down menus at the
top of the window. Next, specify which ports on the Switch are able to receive packets from the port(s) specified in the first step.
Clicking the Apply button will enter the combination of transmitting port(s) and allowed receiving ports into the Switch's Traffic
Segmentation table.

IGMP Snooping

Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and reports sent between
network stations or devices and an IGMP host. When enabled for IGMP snooping, the Switch can open or close a port to a
specific device based on IGMP messages passing through the Switch.

IGMP Snooping Settings

In order to use IGMP Snooping it must first be enabled for the entire Switch under IGMP Global Settings at the top of the
window. You may then fine-tune the settings for each VLAN by clicking the corresponding Edit button. When enabled for IGMP
snooping, the Switch can open or close a port to a specific multicast group member based on IGMP messages sent from the device
to the IGMP host or vice versa. The Switch monitors IGMP messages and discontinues forwarding multicast packets when there
are no longer hosts requesting that they continue.
To view the IGMP Snooping Settings window, click L2 Features > IGMP Snooping Settings.
