Required
By default, a multicast VLAN
has no sub-VLANs.
z You cannot configure multicast VLAN on a device with IP multicast routing enabled.
z The VLAN to be configured as a multicast VLAN must exist.
z The VLANs to be configured as sub-VLANs of the multicast VLAN must exist and must not
be sub-VLANs of any other multicast VLAN.
z The total number of sub-VLANs of a multicast VLAN must not exceed the maximum number
the system can support (an S7500E series Ethernet switch supports up to five multicast
VLANs, and supports up to 4000 sub-VLANs for each multicast VLAN. The total number of
sub-VLANs for all multicast VLANs on the switch cannot exceed 4000.).
Configuring Port-Based Multicast VLAN
When configuring port-based multicast VLAN, you need to configure the attributes of each user
port and then 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
2 aggregate interface type.
z Configurations made in Ethernet interface view is 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 Prerequisites
Before configuring port-based multicast VLAN, complete the following tasks:
z Create VLANs as required
