Multicast VLAN configuration task list
Task Remarks
Configuring a sub-VLAN-based multicast VLAN
Required.
Configuring a port-based
multicast VLAN
Configuring user port attributes
Configuring multicast VLAN ports
Setting the maximum number of forwarding entries in a multicast VLAN Optional.
NOTE:
If you have configured both a sub-VLAN-based multicast VLAN and a port-based multicast VLAN on a
device, the port-based multicast VLAN configuration is given preference.
Configuring a sub-VLAN-based multicast VLAN
Before you configure a sub-VLAN-based multicast VLAN, complete the following tasks:
• Create VLANs as required.
• Enable IGMP snooping in the VLAN to be configured as a multicast VLAN.
In this method, you first configure a VLAN as a multicast VLAN, and configure the VLANs that contain
receivers as sub-VLANs of the multicast VLAN.
When you configure a sub-VLAN-based multicast VLAN, following these guidelines:
• Do not configure a multicast VLAN on a device with IP multicast routing enabled.
• The VLAN to be configured as a multicast VLAN must exist.
• The VLANs to be configured as sub-VLANs of the multicast VLAN must exist and must not be
multicast VLANs or sub-VLANs of any other multicast VLAN.
• The total number of sub-VLANs of a multicast VLAN must not exceed the system upper limit.
To configure a sub-VLAN-based multicast VLAN:
