80.27 Multicast
Traditionally, IP packets are transmitted in one of either two ways – Unicast (1 sender to 1 recipient) or
Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts
on the network.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish membership
in a multicast group
– it is not used to carry user data. Refer to RFC 1112, RFC 2236 and RFC 3376 for
information on IGMP versions 1, 2 and 3 respectively.
This section shows you how to configure various multicast features.
80.27.1 What You Can Do
• Use the IPv4 Multicast Status screen (Section 80.28 on page 661) to view multicast group information.
• Use the IGMP Snooping screen (Section 80.29 on page 662) to enable IGMP snooping to forward
group multicast traffic only to ports that are members of that group.
• Use the IGMP Snooping VLAN screen (Section 80.30 on page 666) to perform IGMP snooping on up to
16 VLANs.
• Use the IGMP Filtering Profile screen (Section 80.31 on page 668) to specify a range of multicast
groups that clients connected to the Switch are able to join.
80.28 IPv4 Multicast Status
Click SWITCHING > Multicast > IPv4 Multicast Status to display the screen as shown. This screen shows the
IPv4 multicast group information.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set the
common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Mirrored Select this option to mirror the traffic on a port.
Direction Specify the direction of the traffic to mirror by selecting from the drop-down list box. Choices are
Egress (outgoing), Ingress (incoming) and Both.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these changes if
it is turned off or loses power, so use the Save link on the top navigation panel to save your changes
to the non-volatile memory when you are done configuring.
Cancel Click Cancel to reset the fields.
