TP-Link TL-SG5412F User Manual

The host, running IGMPv1, does not send IGMP
leave message when leaving a multicast group,
as a result, the switch can not get the leave information of the host momentarily. However, after
leaving the multicast group, the host does not send IGMP report message any more, so the switch
will remove the port from the corresponding multicast address table when its member port time
times out. The host, running IGMPv2 or IGMPv3, sends IGMP leave message when leaving a
multicast group to inform the multicast router of its leaving.
When receiving IGMP leave message, the switch will forward IGMP group-specific-query message
to check if other members in the multicast group of the port need this multicast and reset the
member port time to the leave time. When the leave time times out, the switch will remove the port
from the corresponding multicast group. If no other member is in the group after the port is
removed, the switch will remove the whole multicast group and send IGMP leave message to the
router.
 IGMP Snooping Fundamentals
1. Ports
Router Port: Indicates the switch port directly connected to the multicast router.
Member Port: Indicates a switch port connected to a multicast group member.
2. Timers
Router Port Time: Within the time, if the switch does not receive IGMP query message from the
router port, it will consider this port is not a router port any more. The default value is 300 seconds.
Member Port Time: Within the time, if the switch does not receive IGMP report message from the
member port, it will consider this port is not a member port any more. The default value is 260
seconds.
Leave Time: Indicates the interval between the switch receiving a leave message from a host and
the switch removing the host from the multicast groups. The default value is 1 second.
The IGMP Snooping function can be implemented on Snooping Config, Port Config, VLAN
Config and Multicast VLAN pages.
8.1.1 Snooping Config
To configure the IGMP Snooping on the switch, please firstly configure IGMP global configuration
and related parameters on this page.
If the multicast address of the received multicast data is not in the multicast address table, the
switch will broadcast the data in the VLAN. When Unknown Multicast Discard feature is enabled,
the switch drops the received unknown multicast so as to save the bandwidth and enhance the
process efficiency of the system. Please configure this feature appropriate to your needs.
