Manage Blocking of Unknown Multicast Addresses
As a way to limit unnecessary multicast traffic, you can block multicast traffic from
unknown multicast addresses. If you do this, the switch forwards multicast traffic only
to ports in the multicast group that the switch learned through IGMP snooping. By
default, multicast traffic from unknown addresses is allowed.
To manage blocking of unknown multicast addresses:
1.
Open a web browser from a computer that is connected to the same network as the
switch or to the switch directly through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
The login page displays.
3. Enter the switch password.
The default password is password. The password is case-sensitive.
The HOME page displays.
4.
From the menu at the top of the page, select SWITCHING.
The Quality of Service (QoS) page displays.
5.
From the menu on the left, select MULTICAST.
The MULTICAST page displays.
6.
Enable or disable the blocking of unknown multicast traffic by clicking the button in
the Block Unknown Multicast Address section.
When the blocking of unknown multicast traffic is enabled, the button bar displays
green.
7.
Click the APPLY button.
Your settings are saved.

packets conform to the IGMPv3 standard. By default, IGMPv3 IP header validation is
disabled. If IGMPv3 IP header validation is enabled, IGMPv3 messages must include a
