The multicast-snooping mux-vlan enable command enables a device to transmit Layer 2 multicast traffic on a network configured with MUX VLAN.
The undo multicast-snooping mux-vlan enable command disables a device from transmitting Layer 2 multicast traffic on a network configured with MUX VLAN.
By default, a device is disabled from transmitting Layer 2 multicast traffic on a network configured with MUX VLAN.
Usage Scenario
By default, on a network configured with MUX VLAN, Layer 2 multicast traffic cannot be transmitted between the principal VLAN and subordinate VLANs. You can run the multicast-snooping mux-vlan enable command to enable Layer 2 multicast traffic to be transmitted on the network configured with MUX VLAN.
Precautions
If a MUX VLAN is bound to a static multicast group using the l2-multicast static-group or mld-snooping static-group command, the multicast-snooping mux-vlan enable command cannot be executed. You must delete the association between the MUX VLAN and static multicast group before running the multicast-snooping mux-vlan enable command.
After the multicast-snooping mux-vlan enable command is configured, you cannot run the l2-multicast static-group or mld-snooping static-group command to bind a MUX VLAN to a static multicast group.
