TP-Link TL-SG2424 User Manual page 110

Before configuring a multicast VLAN, you should firstly configure a VLAN as multicast VLAN and
add the corresponding ports to the VLAN on the 802.1Q VLAN page. If the multicast VLAN is
enabled, the multicast configuration for other VLANs on the VLAN Config page will be invalid, that
is, the multicast streams will be transmitted only within the multicast VLAN.
Choose the menu Multicast→IGMP Snooping→Multicast VLAN to load the following page.
The following entries are displayed on this screen:
Multicast VLAN

Multicast VLAN:
VLAN ID:
Router Port Time:
Member Port Time:
Leave Time:
Router Ports:
Note:
1. The router port should be in the multicast VLAN, otherwise the member ports cannot receive
multicast streams.
2. The Multicast VLAN won't take effect unless you first complete the configuration for the
corresponding VLAN owning the port on the 802.1Q VLAN page.
3. Configure the link type of the router port in the multicast VLAN as Tagged otherwise all the
member ports in the multicast VLAN cannot receive multicast streams.
Figure 8-9 Multicast VLAN
Select Enable/Disable Multicast VLAN feature.
Enter the VLAN ID of the multicast VLAN.
Specify the aging time of the router port. Within this time, if the
switch doesn't receive IGMP query message from the router port,
it will consider this port is not a router port any more.
Specify the aging time of the member port. Within this time, if the
switch doesn't receive IGMP report message from the member
port, it will consider this port is not a member port any more.
Specify the interval between the switch receiving a leave message
from a host, and the switch removing the host from the multicast
groups.
Enter the static router port which is mainly used in the network
with stable topology.
