Configuring multicast VLAN ports in interface view or port group view
Follow these steps to configure multicast VLAN ports in interface view or port group view:
To do… Use this command… Remarks
Enter system view system-view —

multicast VLAN and enter multicast
VLAN view
multicast-vlan vlan-id

view
port-group manual
port-group-name
Required
Use either command.
Configure the current port as a
member port of the multicast VLAN port multicast-vlan vlan-id

By default, a user port does not
belong to any multicast VLAN.
NOTE:
•
You cannot configure multicast VLAN on a device with multicast routing enabled.
• The VLAN to be configured as a multicast VLAN must exist.
• A port can belong to only one multicast VLAN.
Configuring the maximum number of forwarding
entries in a multicast VLAN
You can configure the maximum number of entries in the IGMP snooping forwarding table of a multicast
VLAN. When the number of forwarding entries maintained for a multicast VLAN reaches the threshold,
the device creates no more forwarding entries until some entries time out or get manually removed.
Follow these steps to configure the maximum number of entries in the forwarding table
To do... Use the command... Remarks
Enter system view system-view —
Configure the maximum number of
forwarding entries in a multicast
VLAN multicast-vlan entry-limit limit
Required
2000 by default.
NOTE:
If the number of existing entries in the IGMP snooping forwarding table of a multicast VLAN is larger than
the limit when you configure it, the system informs you to remove excessive entries. In this case, the system
does not automatically remove any existing entries or create new entries.
