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 connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
