Example

Scenario 1. IGMP Snooping function

Fig 11-1 Enabling IGMP Snooping function

Example: As shown in the above figure, a VLAN 100 is configured in the switch and includes ports

1, 2, 6, 10 and 12 on slot 1. Four hosts are connected to port 2, 6, 10, 12 respectively and the

multicast router is connected to port 1. As IGMP Snooping is disabled by default either in the switch

or in the VLANs, If IGMP Snooping should be enabled in VLAN 100, the IGMP Snooping should

be first enabled for the switch in Global Mode and in VLAN 100 and set port 1 of VLAN 100 to be

the M-Router port.
