Configuring Multicast Forwarding Defining IGMP Snooping Defining IGMP Snooping When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines: • Which ports want to join which Multicast groups. • Which ports have Multicast routers generating IGMP queries. • Which routing protocols are forwarding packets and Multicast traffic. Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast group is accepting members. This results in the creation of the Multicast filtering database. To enable IGMP Snooping: 1. Click Multicast Support > IGMP.The IGMP Snooping Page opens: Figure 107:IGMP Snooping Page The IGMP Snooping Page contains the following fields: • Enable IGMP Snooping Status - Indicates if IGMP Snooping is enabled on the device. IGMP Snooping can be enabled only if Bridge Multicast Filtering is enabled. The possible field values are: - Checked - Enables IGMP Snooping on the device. - Unchecked - Disables IGMP Snooping on the device. • VLAN ID - Specifies the VLAN ID. • IGMP Snooping Status - Indicates if IGMP snooping is enabled on the VLAN. The possible field values are: - Enable - Enables IGMP Snooping on the VLAN. - Disable - Disables IGMP Snooping on the VLAN. Page 168
