Optional) Configuring Report Message Suppression - TP-Link T1600G-18TS Configuration Manual

Configuring Layer 2 Multicast
IGMP Snooping and MLD Snooping share the setting of Unknown Multicast, so you have
to enable IGMP Snooping globally on the Multicast > IGMP Snooping > Snooping Config
page at the same time.
Follow these steps to configure unknown multicast.
1) Configure Unknown Multicast as Forward or Discard.

Configure the way how the switch processes the multicast data sent to unknown
multicast groups as Forward or Discard. Unknown multicast groups are multicast
groups whose destination multicast address is not in the multicast forwarding
table of the switch.
If this function is enabled, the switch will only forward the first MLD report
message to Layer 3 devices and suppress subsequent MLD report messages
from the same multicast group during one query interval, which reduces the
number of MLD packets.
Router ports are ports connected to Layer 3 devices on the switch. The router
port ages if the switch does not receive MLD query message from the router port
within the router port time. The switch will no longer consider this port as a router
port and delete it from the router port table. The valid values are from 60 to 600
seconds.
Member ports are ports connected to multicast group members on the switch.
A port is considered to be a member port when it is added to a multicast group.
The member port ages if the switch does not receive MLD membership report
message from the member port within the member port time. The switch will
no longer consider this port as a member port and delete it from the multicast
forwarding table. The valid values are from 60 to 600 seconds.
