Customize IGMP Snooping

By default, IGMP snooping is enabled. You can customize the settings for your network.

To customize IGMP snooping:

1. Connect your computer to the same network as the switch.

You can use a WiFi or wired network connection, or connect directly to a switch that
is off-network using an Ethernet cable.

2. Launch a web browser.

3. In the address field of your web browser, enter the IP address of the switch.

The login page displays.

4. Enter the switch password.

The default password is

password

. The password is case-sensitive.

The Switch Information page displays.

5. Select

System > Multicast

.

The IGMP Snooping Configuration page displays.

6. Make sure that the IGMP Snooping Status

Enable

radio button is selected.

By default, the

Enable

radio button is selected.

7. In the

VLAN ID Enabled for IGMP Snooping

field, enter a VLAN ID between 1 and

4094.
By default, the VLAN ID is 1.

You can specify a VLAN for IGMP snooping only if you enabled port-based or
802.1Q-based VLANs (see Use VLANS for Traffic Segmentation on page 29).

IGMP snooping functions only on the VLAN that is specified in the

VLAN ID Enabled

field.

8. (Optional) Select the Validate IGMPv3 IP header

Enable

radio button.

Some network devices might not conform to the IGMPv3 standard. When the Validate
IGMPv3 IP header option is enabled, IGMP messages are required to include TTL =
1, ToS Byte = 0xC0 (Internetwork Control), and the router alert IP option (9404) must
be set. Otherwise, the packets are ignored.

9. (Optional) Select the Block Unknown MultiCast Address

Enable

radio button.

When this feature is enabled, multicast packets are forwarded only to the ports that
are in the multicast group learned from IGMP snooping. All unknown multicast
packets are dropped.
