Chapter 40 Commands for Multicast
VLAN
40.1 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
40.2 multicast-vlan association
Command: multicast-vlan association
no multicast-vlan association
Function: Associate several VLANs with a multicast VLAN; the “no” form of this command cancels the
association relations.
Parameter: 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
