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.
Choose the menu
Multicast
IGMP Snooping
Snooping Config
to load the following page.
Figure 8-5 Basic Config
The following entries are displayed on this screen:
Global Config
IGMP Snooping:
Select Enable/Disable IGMP Snooping function globally on the
switch.
Unknown Multicast:
Select the operation for the switch to process unknown multicast,
Forward or Discard.
Report
Message
Suppression:
Enable or disable Report Message Suppression function globally.
If this function is enabled, the first Report Message from the
listener will be forwarded to the router ports while the subsequent
Report Message will be suppressed to reduce the IGMP packets.
Router Port Time:
Specify the aging time of the router port. Within this 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.
