DGS-3630 Series Layer 3 Stackable Managed Switch Web UI Reference Guide The fields that can be configured are described below: Parameter Interface VLAN Group Description Enter the VLAN interface ID here. The range is from 1 to 4094. Enter the IP multicast group address here. Click the Apply button to accept the changes made. Click the Find button to locate a specific entry based on the information entered. Click the Show All button to display all the entries. IGMP Dynamic Group Table This window is used to find, clear and display IGMP dynamic group information. The IGMP buffer includes a list that contains the dynamic multicast groups that the hosts in the direct subnet join. Use this window to clear the dynamic group information. To view the following window, click L3 Features > IP Multicast Routing Protocol > IGMP > IGMP Dynamic Group Table, as shown below: Figure 6-90 IGMP Dynamic Group Table Window The fields that can be configured are described below: Parameter Interface VLAN Group Description Enter the VLAN interface ID here.

Click the Clear button to clear the entries based on the information specified. Click the Show All button to display all the entries. Click the Clear All button to clear all the entries. IGMP SSM Mapping Settings This window is used to display and configure the IGMP SSM mapping settings. The deployment of Source Specific Multicast (SSM) allows the network service provider to manage IP multicast addresses easily. When SSM is enabled, the last hop router will establish a source-based tree for the channel (S, G) on receiving a (S, G) INCLUDE request that falls in the SSM range from the attached IGMPv3 hosts. There are cases that the attached host is IGMPv1 or IGMPv2 hosts which only issue (*, G) requests. With the SSM mapping, if the multicast group being requested falls in the SSM range, the router is able to map the (*, G) to a (S, G) request based on the group address to source address mapping defined here. The router will then establish the source-based tree for the mapped (S, G). If multiple associations exist, the router will establish a (S, G) source-based tree for each S. 302
