CHAPTER 31 IP Multicast This chapter shows you how to configure the IP Multicast screen. 31.1 IP Multicast Overview Traditionally, IP packets are transmitted in one of either two ways - Unicast (one sender to one recipient) or Broadcast (one sender to everybody on the network). IP Multicast is a third way to deliver IP packets to a group of hosts on the network - not everybody. You can configure the Switch to untag (remove the VLAN tags from) IP multicast packets that the Switch forwards. This allows the Switch to send packets to Ethernet devices that are not VLAN-aware. 31.2 Configuring Multicast Click IP Application > IP Multicast in the navigation panel to display the screen as shown next. Figure 138 IP Application > IP Multicast The following table describes the labels in this screen. ES-4124 User's Guide 255
