Alternatively, you can statically bind a port to a multicast MAC address entry byconfiguring a multicast MAC address entry manually.Generally, when receiving a multicast packet for a multicast group not yet registered on the switch, theswitch will flood the packet within the VLAN to which the port belongs. You can configure a staticmulticast MAC address entry to avoid this.Follow these steps to configure a multicast MAC address entry in system view:To do... Use the command...
