1. 8 1 4 Multicast VLAN In old multicast transmission mode when users in different VLANs apply for join the same multicast group the multicast router will duplicate this multicast information and deliver each 82 VLAN owning a receiver one copy This mode wastes a lot of bandwidth The problem above can be solved by configuring a multicast VLAN By adding switch ports to the multicast VLAN and enabling IGMP Snooping you can make users in different VLANs share the same multicast VLAN This saves the bandwidth since multicast streams are transmitted only within the multicast VLAN and also guarantees security because the multicast VLAN is isolated from user VLANS Before configuring a multicast VLAN you should firstly configure a VLAN as multicast VLAN and add the corresponding ports to the VLAN on the 802 1Q VLAN page If the multicast VLAN is enabled the multicast configuration for other VLANs on the VLAN Config page will be invalid that is the multicast streams will be transmitted only within the multicast VLAN Choose the menu Multicast IGMP Snooping Multicast VLAN to load the following page Multicast VLAN Multicast VLAN VLAN ID Router Port Time Member Port Time Leave Time Router Ports Note Enable Disable 2 4094 sec 60 600 recommend 300 Apply sec 60 600 recommend 260 sec 1 30 recommend 1 Format 1 3 6 8 1 All IGMP packet will be processed in the Multica
