Configuring a Multicast MAC Address Entry

In Layer 2 multicast, the system can add multicast forwarding entries dynamically through a Layer 2
multicast protocol. Alternatively, you can statically bind a port to a multicast MAC address entry by
configuring a multicast MAC address entry manually.
Generally, when receiving a multicast packet for a multicast group not yet registered on the switch, the
switch will flood the packet within the VLAN to which the port belongs. You can configure a static
multicast MAC address entry to avoid this.
Follow these steps to configure a multicast MAC address entry in system view:
To do...
Enter system view
Create a multicast MAC
address entry
Follow these steps to configure a multicast MAC address entry in Ethernet port view:
To do...

Use the command...
reset multicast forwarding-table
[ statistics ] { all | { group-address [ mask
{mask | mask-length } ] | source-address
[ mask { mask |mask-length } ] |
incoming-interface interface-type
interface-number } * }
reset multicast routing-table { all |
{ group-address [ mask { mask
|mask-length } ] | source-address [ mask
{ mask | mask-length } ] |
{ incoming-interface interface-type
interface-number } } * }
Use the command...
