[. . . ] If the IGMP report matches one of the configured MVR multicast group addresses on the Switch, an entry is created in the forwarding table on the Switch. This maps the subscriber VLAN to the list of forwarding destinations for the specified multicast traffic. When the subscriber changes the channel or turns off the computer, an IGMP leave message is sent to the Switch to leave the multicast group. The Switch sends a query to VLAN 1 on the receiver port (in this case, an uplink port on the Switch). If there is another subscriber device connected to this port in the same subscriber VLAN, the receiving port will still be on the list of forwarding destination for the multicast traffic. Otherwise, the Switch removes the receiver port from the forwarding table. Figure 104 MVR Multicast Television Example 23. 2 Multicast Status Click Advanced Applications > Multicast to display the screen as shown. This screen shows the multicast group information.

Table 55 Advanced Application > Multicast Status LABEL Index VID Port Multicast Group DESCRIPTION This is the index number of the entry. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Note: Changes in this row are copied to all the ports as soon as you make them. Immed. Leave Select this option to set the Switch to remove this port from the multicast tree when an IGMP version 2 leave message is received on this port. Select this option if there is only one host connected to this port. Normal Leave Enter an IGMP normal leave timeout value (from 200 to 6, 348, 800) in miliseconds. Select this option to have the Switch use this timeout to update the forwarding table for the port. This defines how many seconds the Switch waits for an IGMP report before removing an IGMP snooping membership entry when an IGMP leave message is received on this port from a host. Fast Leave Enter an IGMP fast leave timeout value (from 200 to 6, 348, 800) in miliseconds. Select this option to have the Switch use this timeout to update the forwarding table for the port. This defines how many seconds the Switch waits for an IGMP report before removing an IGMP snooping membership entry when an IGMP leave message is received on this port from a host. Group Limited Select this option to limit the number of multicast groups this port is allowed to join. 172 GS2200-8/24 User’s Guide Chapter 23 Multicast Table 56 Advanced Application > Multicast > Multicast Setting (continued) LABEL Max Group Num.
