Item Description
VLAN ID The VLAN associated with the rest of the data in the row. When
enabling IGMP snooping on a VLAN, use this menu to select the
desired VLAN. Only VLANs that have been configured on the system
and 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.
Fast Leave Admin
Mode The administrative mode of Fast Leave on the VLAN. If Fast Leave is
enabled, the VLAN can be immediately removed from the layer 2 for-
warding table entry upon receiving an IGMP leave message for a mul-
ticast group without first sending out MAC-based general queries.
Group Membership
Interval (Seconds) The number of seconds the VLAN should wait for a report for a particu-
lar group on the VLAN before the IGMP snooping feature deletes the
VLAN from the group.
Max Response Time
(Seconds) The number of seconds the VLAN should wait after sending a query if
it does not receive a report for a particular group. The specified value
should be less than the Group Membership Interval.
Multicast Router
Expiration Time
(Seconds) The number of seconds the VLAN should wait to receive a query
before it is removed from the list of VLANs with multicast routers
attached.
Report Suppression
Mode 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.
