Static Multicast MAC 
Address Overview
The concept of "static multicast MAC address" is proposed to fulfill the feature of 
static Layer 2 multicast. When some network users need some specific 
information, the multicast information sender (the multicast source) sends the 
information only once, and the multicast packets are sent to the specified port 
with the help of the configured static multicast MAC address.

Multicast MAC 
Address
Configuration 
Prerequisites
The port to be configured and the VLAN both exist;
The port to be configured is within the specified VLAN.
Configuring a Static 
Multicast MAC Address
CAUTION:
Do not enable the PIM on the virtual interface of the VLAN to be configured.
The multicast MAC address to be configured must not be a multicast MAC 
address used by a known protocol.
The port to be configured must be an Ethernet port.
The port to be configured must not be aggregate port.
If the MAC address to be configured already exists, the specified port will be 
addedto the existing MAC group. This does not affect other ports existing in 
the group.
