Context
According to the version of IGMP applied on a network, you can configure the S9300 enabled
with IGMP snooping to process IGMP messages of the corresponding version.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
vlan vlan-id
The VLAN view is displayed.
Step 3 (Optional) Run:
igmp-snooping version version
The version of IGMP messages that can be processed is configured for the S9300 enabled with
IGMP snooping.
By default, the S9300 runs IGMPv2, which is backward compatible. That is, the S9300 can
process IGMPv1 messages but cannot process IGMPv3 messages. The S9300 provides
transparent transmission of the IGMPv3 messages.
CAUTION
When the forwarding in a VLAN is based on the MAC address, the IGMP message version
cannot be set to IGMPv3.

1.6.4 (Optional) Setting the Forwarding Mode of Multicast Data in
a VLAN
Context
You can set the forwarding mode of multicast data so that the multicast flows can be forwarded
based on IP addresses or MAC addresses. When multicast IP addresses are mapped to MAC
addresses, up to 32 IP addresses can be mapped to one MAC address. Therefore, it is
recommended that multicast data be forwarded based on IP addresses; otherwise, unregistered
users may receive the multicast data.
