Description
Use the service-type multicast command to configure the current VLAN as
multicast VLAN.
Use the undo service-type multicast command to remove the configuration.
By default, all VLANs are not multicast VLANs.
If you configure multicast VLAN, add the corresponding switch ports to the
multicast VLAN and enable IGMP Snooping, users in different VLANs can share
one multicast VLAN, and multicast flow can be transmitted in the multicast VLAN
only, thus saving bandwidth. The completely isolated multicast VLAN and user
VLAN can effectively ensure security.
n
A port can belong to only one multicast VLAN.
■
The type of port connected with user terminals must be hybrid untagged.
■
The current system supports up to three multicast VLANs.
■
Example
# Configure VLAN 2 as multicast VLAN.
<SW8800> system-view
