Figure 7- 8. Port Trunking Configuration window

The user-changeable parameters are as follows:

Parameter Description

Group ID [1-4] Select an ID number for the group, between 1 and 4.

State Trunk groups can be toggled between Enabled and Disabled. This is used to turn a

port trunking group on or off. This is useful for diagnostics, to quickly isolate a

bandwidth intensive network device or to have an absolute backup aggregation

group that is not under automatic control.

Type The type of port trunking supported by the DGS-3024 is Static.

Master Port Choose the Master Port for the trunk group using the pull-down menu.

Port Map Choose the members of a trunked group. Up to eight ports per group can be

assigned to a group.

Active Port Shows the port that is currently forwarding packets.

After setting the previous parameters, click Apply to allow your changes to be implemented. Successfully created trunk

groups will be show in the Current Trunking Group Entries 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.

In order to use IGMP Snooping it must first be enabled for the entire Switch on the Switch Information (Advanced

Settings) window (Configuration > Advanced Settings). You may then fine-tune the settings for each VLAN by clicking

the IGMP Snooping link in the Configuration folder. 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.
