Chapter 3 COMMANDS FOR MULTICAST VLAN

3.1 multicast-vlan

 Command: multicast-vlan

 no multicast-vlan

 Function: Enable multicast VLAN function on a VLAN; the “no” form of this command

disables the multicast VLAN function.

 Parameter: None.

 Command Mode: VLAN Configuration Mode.

 Default: Multicast VLAN function not enabled by default.

 Usage Guide: The multicast VLAN function can not be enabled on Private VLAN. To

disabling the multicast VLAN function of the VLAN, configuration of VLANs associated

with the multicast VLAN should be deleted. Note that the default VLAN can not be

configured with this command and only one multicast VLAN is allowed on a switch.

 Examples:

 Switch(config)#vlan 2

 Switch(Config-Vlan2)# multicast-vlan

3.2 multicast-vlan association

 Command: multicast-vlan association <vlan-list>

 no multicast-vlan association <vlan-list>

 Function: Associate several VLANs with a multicast VLAN; the “no” form of this

command cancels the association relations.

 Parameter: <vlan-list> the VLAN ID list associated with multicast VLAN. Each VLAN can

only be associated with one multicast VLAN and the association will only succeed when

every VLAN listed in the VLAN ID table exists.

 Command Mode: VLAN Mode.

 Default: The multicast VLAN is not associated with any VLAN by default.

 Usage Guide: After a VLAN is associated with the multicast VLAN, when there comes

the multicast order in the port of this VLAN, then the multicast data will be sent from

the multicast VLAN to this port, so to reduce the data traffic. The VLAN associated with

the multicast VLAN should not be a Private VLAN. A VLAN can only be associated with

another VLAN after the multicast VLAN is enabled. Only one multicast VLAN can be

enabled on a switch.

 Examples:

 Switch(config)#vlan 2

 Switch(Config-Vlan2)# multicast-vlan association 3, 4
