Configuring multicast VLAN ports
In this approach, you configure a VLAN as a multicast VLAN and assign user ports to it. You can do it
by either adding the user ports in the multicast VLAN or specifying the multicast VLAN on the user ports.
These two methods provide the same result.
When you configure multicast VLAN ports, follow these guidelines:
• Do not configure a multicast VLAN on a device with multicast routing enabled.
• The VLAN to be configured as a multicast VLAN must exist.
• A port cannot belong to multiple multicast VLANs.
Adding the user ports to the multicast VLAN

Command Remarks
1. Enter system view.
system-view N/A
2. Configure the specified VLAN
as a multicast VLAN and enter
multicast VLAN view.
multicast-vlan vlan-id
By default, a VLAN is not a
multicast VLAN.
3. Assign ports to the multicast
VLAN.
port interface-list
By default, a multicast VLAN has
no ports.
Specifying the multicast VLAN on the user ports
Ste

Command Remarks
1. Enter system view. system-view N/A
2. Configure the specified VLAN
as a multicast VLAN and enter
multicast VLAN view.
multicast-vlan vlan-id
A VLAN is not a multicast VLAN by
default.
3. Return to system view.
quit N/A
4. Enter interface view or port
group view.
• Enter interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
5. Assign the current port to the
multicast VLAN.
port multicast-vlan vlan-id
By default, a user port does not
belong to any multicast VLAN.
Setting 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 age out or are manually removed.
