Configuring Sub-Vlan-Based Multicast Vlan; Configuring Port-Based Multicast Vlan - 3Com S7906E Configuration Manual

Configuring Sub-VLAN-Based Multicast VLAN

In this approach, you need to configure a VLAN as a multicast VLAN, and then configure user VLANs as
sub-VLANs of the multicast VLAN.
Follow these steps to configure sub-VLAN-based multicast VLAN:
To do...
Enter system view
Configure the specified VLAN
as a multicast VLAN and enter
multicast VLAN view
Configure the specified
VLAN(s) as sub-VLAN(s) of the
multicast VLAN
You cannot configure 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
sub-VLANs of any other multicast VLAN.
The total number of sub-VLANs of a multicast VLAN must not exceed the maximum number the
system can support (an S7900E 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.
A user port can be configured as a multicast VLAN port only if it is of the Ethernet, or Layer 2
aggregate interface type.
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.
Use the command...
system-view
multicast-vlan vlan-id
subvlan vlan-list
1-4
Remarks
—
Required
Not a multicast VLAN by default
Required
By default, a multicast VLAN
has no sub-VLANs.
