Configure IGMP Snooping Internet Group Management Protocol (IGMP) snooping reduces duplicate and
excess traffic on the network by forwarding IP multicast traffic to specific switch
ports rather than by flooding all ports.
With IGMP snooping, ports that are members of only specific IP multicast
groups receive multicast messages. The result is a more efficient use of
bandwidth.
To configure IGMP snooping, from the Configure menu, choose
IGMP Snooping:
• To enable IGMP Snooping for all VLAN IDs, check Enable next to IGMP
Snooping.
• To enable IGMP Querier for all VLAN IDs, check Enable next to IGMP
Querier.
• To enable or disable IGMP snooping on a VLAN, select the VLAN and
check or clear the Enable IGMP Snooping checkbox.
