8.5 Static Multicast Screen
Click Multicast > Static Multicast in the navigation panel to display the screen shown next.
Use static multicast to allow incoming frames based on the VID and multicast MAC address(es).
This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es)
that are not learned by IGMP snooping or IGMP proxy and would otherwise be dropped. Use static
multicast to pass routing protocols, such as RIP and OSPF.
For your convenience this screen lets you input IPv4 multicast addresses and the MSC converts
them to multicast MAC addresses internally. See
Section 8.6 on page 196 if you need to configure
other types of MAC address (such as IPv6).

Index This column lists the slot numbers of the line cards. Click the number of an active line card to
go to a screen where you can set the membership of each of the card’s ports for this static
multicast group.
Card Type This field displays the kind of card installed in a slot.
Port This section lists the VLAN membership setting of each port on each line card. An “F”
indicates that the port is a permanent member of the static multicast group. An “X” indicates
that the port is forbidden (blocked) from joining the static multicast group. An “-” indicates
that the port is a normal member and can join the group dynamically.
