Configuring Port-Based Multicast Vlan; Configuration Prerequisites; Configuring User Port Attributes - HP A5500 SI Switch Series Configuration Manual

NOTE:
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.

Configuring port-based multicast VLAN

When you configure port-based multicast VLAN, you must configure the attributes of each user port and
then assign the ports to the multicast VLAN.
NOTE:
A user port can be configured as a multicast VLAN port when if it is an Ethernet interface or Layer 2
aggregate interface.
In Ethernet interface view or Layer 2 aggregate interface view, configurations that you make are
effective only on the current interface. In port group view, configurations that you make are effective
on all ports in the current port group.

Configuration prerequisites

Before you configure port-based multicast VLAN, complete the following tasks:
Create VLANs as required
•
Enable IGMP snooping in the VLAN to be configured as a multicast VLAN
•
Enable IGMP snooping in all user VLANs
•

Configuring user port attributes

Configure the user ports as hybrid ports that permit packets of the specified user VLAN to pass, and
configure the user VLAN to which the user ports belong as the default VLAN.
Configure the user ports to permit packets of the multicast VLAN to pass and untag the packets. After the
configuration, upon receiving multicast packets tagged with the multicast VLAN ID from the upstream
device, the Layer 2 device untags the multicast packets and forwards them to its downstream device.
Follow these steps to configure user port attributes:
To do...
Enter system view
Enter interface view or port group
view
Configure the user port link type
as hybrid
