Parameters
None
Description
Use the service-type multicast command to configure the current VLAN as a multicast VLAN.
Use the undo service-type multicast command to remove the current VLAN as a multicast VLAN.
By default, no VLAN is a multicast VLAN.
In an IGMP Snooping environment, by configuring a multicast VLAN and adding ports to the multicast
VLAN, you can allow users in different VLANs to share the same multicast VLAN. This saves bandwidth
because multicast streams are transmitted only within the multicast VLAN. In addition, because the
multicast VLAN is isolated from user VLANs, this method also enhances the information security.
