are not already enabled for IGMP snooping appear in the menu. When modifying IGMP snooping
settings, this field identifies the VLAN that is being configured.
The administrative mode of IGMP snooping on the VLAN. IGMP snooping must be enabled globally
and on an VLAN for the VLAN to be able to snoop IGMP packets to determine which network
segments should receive multicast packets directed to the group address.
The administrative mode of Fast Leave on the VLAN. If Fast Leave is enabled, the VLAN can be
immediately removed from the Layer-2 forwarding table entry upon receiving an IGMP leave message
for a multicast group without first sending out MAC-based general queries.
The number of seconds the VLAN should to wait for a report for a particular group on the VLAN before
the IGMP snooping feature deletes the VLAN from the group.
The number of seconds the VLAN should wait after sending a query if does not receive a report for a
particular group. The specified value should be less than the Group Membership Interval.
The number of seconds the VLAN should wait to receive a query before it is removed from the list of

The IGMPv1 and IGMPv2 report suppression mode. The device uses IGMP report suppression to limit
the membership report traffic sent to multicast-capable routers. When this mode is enabled, the
device does not send duplicate reports to the multicast router. Note that this mode is supported only
when the multicast query has IGMPv1 and IGMPv2 reports. This feature is not supported when the
query includes IGMPv3 reports. The options are as follows:
• Enabled Only the first IGMP report from all hosts for a group IGMP report is forwarded to the
multicast routers.
• Disabled The device forwards all IGMP reports from all hosts in a multicast group to the multicast
routers.
