Configure IGMP snooping settings
Multicast > IGMP Snooping > Property
Configure IGMP snooping settings for IPv4 multicast traffic.
1. Log into your switch management page (see “Access your switch management page”
on page 11).
2. Click on Multicast, click on IGMP Snooping, and click Property.
3. Review the settings. Click on Apply to save the configuration changes.
• State: Check the Enable option to enable IGMP snooping. Uncheck to disable
IGMP snooping.
• Version: Select the IGMP snooping version. IGMPv2 or IGMPv3.
• Report Supression: Enable the report suppression option to limit the amount
of IGMP multicast reports to the multicast router to reduce multicast traffic
overhead.
Under the VLAN Setting table, the active VLANs will be listed. To edit the IGMP snooping
settings for a specific VLAN, select the VLAN and click Edit.
• State: Check the Enable option to enable IGMP snooping for the specific VLAN.
Uncheck to disable IGMP snooping.
• Router Port Auto Learn: Check the Enable option to configure the router
port(s) to be dynamically learned by the switch for the specific VLAN
• Immediate Leave: Check the Enable option to enable IGMP immediate leave
for IGMP snooping. Enabling this option allows the switch to remove an
interface from the forwarding table without first sending out IGMP group
specific queries to the interface and the VLAN interface can be removed from
the multicast tree to ensure optimal bandwidth for multicast traffic.
• Version: Select the IGMP snooping version. IGMPv2 or IGMPv3.
• Report Supression: Enable the report suppression option to limit the amount
of IGMP multicast reports to the multicast router to reduce multicast traffic
overhead.
• Query Robustness: Enter the the variable number of unacknowledged
snooping queries that switch can send before removing the multicast client
from the group list. Default: 2, Range: 1-7
• Query Interval: Enter the interval time/period between each IGMP
membership query message the switch will send out. Default: 125, Range: 30-
18000
• Query Response Interval: Enter the interval time/period the switch will wait for
an IGMP response after each IGMP membership query message is sent out by
the switch. Default: 10, Range: 5-20
• Last Member Query Counter: Enter the number of query messages the router
sends in response to an IGMP leave message. Default: 2, Range: 1-7
• Last Member Query Interval: Enter the interval time/period for sending query
messages to active IGMP interfaces. Default: 1, Range: 1-25
• Operational Status: Displays a summary of all the IGMP snooping configuration
settings.
