Static Multicast MAC Configuration
The following options are available to control the forwarding of known and unknown multicast
packets:
 All multicast packets are flooded to the entire VLAN. This is the default switch behavior.
 Known multicast packets are forwarded only to those ports specified. Unknown multicast
packets are flooded to the entire VLAN. To configure this option, define the Multicast MAC
address for the VLAN and specify ports that are to receive multicast packets
(mac-address-table multicast).
 Known multicast packets are forwarded only to those ports specified. Unknown multicast
packets are dropped. To configure this option:
 Define the Multicast MAC address for the VLAN and specify ports that are to receive
multicast packets (mac-address-table multicast).
 Enable Flood Blocking on ports that are not to receive multicast packets (interface
port x) (flood-blocking).
Use the following commands to configure static Multicast MAC entries in the Forwarding Database
(FDB).
