The total number of sub-VLANs for all multicast VLANs onthe switch cannot exceed 1024..Configuring Port-Based Multicast VLANWhen configuring port-based multicast VLAN, you need to configure the attributes of each user port andthen assign the ports to the multicast VLAN.z A user port can be configured as a multicast VLAN port only if it is of the Ethernet, or Layer 2aggregate interface type.z Configurations made in Ethernet interface view are effective only for the current port;configurations made in Layer 2 aggregate interface view are effective only for the current interface;configurations made in port group view are effective for all the ports in the current port group.Configuration PrerequisitesBefore configuring port-based multicast VLAN, complete the following tasks:z Create VLANs as requiredz Enable IGMP Snooping in the VLAN to be configured as a multicast VLANz Enable IGMP Snooping in all the user VLANs
