IGMP Snooping allows the switch to forward multicast traffic only to those ports that request it. IGMP
Snooping prevents multicast traffic from being flooded to all ports. The switch learns which server hosts
are interested in receiving multicast traffic, and forwards it only to ports connected to those servers.
The following table describes the IGMP Snooping Configuration controls:

Descriptions
Enables or disables IGMP Snooping.
Configures the timeout value for IGMP Membership Reports (host). Once the timeout
value is reached, the switch removes the host from its IGMP table, if the conditions
are met. The range is from 1 to 255 seconds. The default is 10 seconds.
Configures the timeout value for IGMP Membership Queries (Mrouter). Once the
timeout value is reached, the switch removes the multicast router from its IGMP
table, if the proper conditions are met. The range is from 1 to 255 seconds. The
default is 255 seconds.
Configures the IGMP Robustness variable, which allows you to tune the switch for
expected packet loss on the subnet. If the subnet is expected to be lossy (high rate of
packet loss), increase the value. The range is from 2 to 10. The default value is 2.
Sets the IGMP router query interval, in seconds. The default value is 125.
Enables or disables IGMP Membership Report aggregation.
Configures the switch to flood unregistered IP multicast reports to all ports.
Configures the source IP address used as a proxy for IGMP Group Specific Queries.
Removes all VLANs from the list of Snooping VLANs.
Enables or disables IGMP version 3. The default value is disabled.
Configures the maximum number of IGMP multicast sources to snoop from within the
group record. Use this command to limit the number of IGMP sources to provide
more refined control.
Enables or disables snooping on IGMPv3 Exclude Reports. When disabled, the
switch ignores Exclude Reports. The default value is enabled.
Enables or disables snooping on IGMP version 1 and version 2 reports. When
disabled, the switch drops IGMPv1 and IGMPv2 reports. The default value is
enabled.
Lists the VLANs that can be assigned for IGMP Snooping.
Enables or disables IGMP Snooping on selected VLANs.
Add: Adds selected VLANs to the Snooping VLANs list. To add a VLAN, select the
VLAN in the Configured VLANs list, and click Add.
Remove: Removes selected VLANs from the Snooping VLANs list.
Lists the Snooping VLANs that can be assigned for Fstleave processing.
