For details, please refer to Configuring 802.1Q VLAN. The switch supports configuring IGMP Snooping on a per-VLAN basis. After IGMP Snooping is enabled globally, you also need to enable IGMP Snooping and configure the corresponding parameters for the VLANs that the router ports and the member ports are in. Follow these steps to configure IGMP Snooping for VLANs: Step 1 Step 2 configure Enter global configuration mode. ip igmp snooping vlan-config vlan-id-list mtime member-time Enable IGMP Snooping for the specified VLANs, and specify the member port aging time for the VLANs. vlan-id-list: Specify the ID or the ID list of the VLAN(s). member-time: Specify the aging time of the member ports in the specified VLANs. Valid values are from 60 to 600 seconds. By default, it is 260 seconds. Once the switch receives an IGMP membership report message from a port, the switch adds this port to the member port list of the corresponding multicast group. Member ports that are learned in this way are called dynamic member ports. If the switch does not receive any IGMP membership report message for a specific multicast group from a dynamic member port, it will no longer consider this port as a member port of this multicast group and delete it from the multicast forwarding table.
