NETGEAR MS108EUP - Enable a VLAN for IGMP Snooping; Manage Blocking of Unknown Multicast Addresses

Enable a VLAN for IGMP snooping
You can enable IGMP for a VLAN only if you enabled a port-based VLAN mode or an
802.1Q VLAN mode (see Use
VLANS for Traffic Segmentation on page 32.
To enable IGMP snooping for a VLAN:
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.
The HOME page displays.
4.
From the menu at the top of the page, select SWITCHING.
The QOS page displays.
5.
From the menu on the left, select MULTICAST.
The MULTICAST page displays.
6.
In the VLAN ID Enabled for IGMP Snooping section, enter a VLAN ID in the field.
If you enabled either a port-based VLAN mode or an 802.1Q VLAN mode, the default
VLAN for IGMP snooping is VLAN 1.
7. Click the APPLY button.
Your settings are saved.
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.
