Operation Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
By configuring a multicast VLAN, adding switch ports to the multicast VLAN and
enabling IGMP Snooping, you can make users in different VLANs share the same
multicast VLAN. This saves bandwidth since multicast streams are transmitted only
within the multicast VLAN, and also guarantees security because the multicast VLAN is
isolated from user VLANs.
Multicast VLAN is mainly used in Layer 2 switching, but you must make corresponding
configuration on the Layer 3 switch.
Perform the following configuration to configure multicast VLAN.
