IP Multicast
This chapter shows you how to configure the IP Multicast screen.
28.1 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.
28.2 Configuring
Click IP Application and IP Multicast in the navigation panel to display the screen as shown
