Static Multicast Forward Setup
Use these screens to configure static multicast address forwarding.
11.1  Static Multicast Forwarding Overview
A multicast MAC address is the MAC address of a member of a multicast group. A 
static multicast address is a multicast MAC address that has been manually 
entered in the multicast table. Static multicast addresses do not age out. Static 
multicast forwarding allows you (the administrator) to forward multicast frames to 
a member without the member having to join the group first.
If a multicast group has no members, then the switch will either flood the 
multicast frames to all ports or drop them. You can configure this in the 
Advanced Application > Multicast > Multicast Setting screen (see 
). 
 shows such unknown multicast frames flooded to all 
ports. With static multicast forwarding, you can forward these multicasts to 
port(s) within a VLAN group.
