• Membership Interval. Specify the value for the group membership interval of
IGMP snooping for the VLAN. The value must be the value in the Maximum
Response Time field plus a value of 1 to 3600 seconds.
• Maximum Response Time. Specify the value for the maximum response time of
IGMP snooping for the VLAN.
The range must be from 1 to the value in the Group
Membership Interval field minus 1. The value in the Maximum Response Time
must be greater than the value in the Group Membership Interval field.
• Multicast Router Expiry Time. Specify the value of the multicast router expiration
time of IGMP snooping for the VLAN.
The range must be from 0 to 3600 seconds.
• Report Suppression. From the menu, select to enable or disable the IGMP
snooping report suppression mode for the VLAN.
This mode allows for the
suppression of IGMP reports that are sent by multicast hosts. The switch does so
by building a Layer 3 membership table and sending only the essential reports to
IGMP routers that must receive the multicast traffic. As a result, the multicast
report traffic that is sent to the IGMP routers is reduced. The default is Disable.
• Proxy Querier. From the menu, select to enable or disable the proxy querier for
the VLAN. If disabled, the IGMP proxy query with source IP address 0.0.0.0 is not
sent in response to an IGMP leave packet.
The default is Enable.
• Report Flood Mode. From the menu, select to enable or disable the report
flooding mode on the VLAN. If enabled, IGMP Join/Leave PDUs that the VLAN
receives from a host on a downstream port are forwarded to all other ports in the
VLAN.
The default is Enable.
• Exclude Mrouter Interface Mode. From the menu, select to enable or disable the
Exclude Mrouter Interface Mode.
This selection specifies the type of information
that is forwarded to the upstream multicast router interface.
If enabled, the VLAN forwards IGMP Join/Leave PDUs that it receives on a
downstream port to an upstream mrouter interface. In addition, the VLAN forwards
a multicast data stream to an upstream mrouter interface only if that port already
received an IGMPv1 or IGMPv2 membership message.
The VLAN drops
unknown multicast streams. The default is Enable.
If disabled, the VLAN forwards IGMP Join/Leave PDUs, known multicast streams,
and unknown multicast streams to the upstream mrouter interface.

IGMP Snooping for VLANs Automatically with IGMP Plus Mode on
