Configuring A Port-Based Multicast Vlan; Configuration Prerequisites; Configuring User Port Attributes - H3C S5500-EI Configuration Manual

Step
1. Enter system view.
2. Configure the specified VLAN
as a multicast VLAN and enter
multicast VLAN view.
3. Configure the specified
VLANs as sub-VLANs of the
multicast VLAN.

Configuring a port-based multicast VLAN

When you configure a port-based multicast VLAN, you must 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 an Ethernet port, or Layer 2 aggregate
interface.
In Ethernet interface view or Layer 2 aggregate interface view, configurations that you make are effective
on only the current port. In port group view, configurations that you make are effective on all ports in the
current port group.

Configuration prerequisites

Before you configure a 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 the user VLANs.
•

Configuring user port attributes

First, 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.
Then, configure the user ports to permit packets of the multicast VLAN to pass and untag the packets.
Thus, after 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.
To configure user port attributes:
Step
1. Enter system view.

By default, a VLAN is not a
multicast VLAN.
By default, a multicast VLAN has
no sub-VLANs.
