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

multicast forwarding allows you (the administrator) to forward multicast frames to

multicast frames to all ports or drop them. You can configure this in the
Advanced Application > Multicast > Multicast Setting screen (see
