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 27).
IGMP snooping functions only on the VLAN that is specified in the VLAN ID Enabled
for IGMP Snooping 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.
10.
(Optional, for some models only) Select an option from the IGMP Snooping Static
Router Port menu.
You can select a port to be the dedicated IGMP snooping static router port if no
IGMP query exists in the network for the switch to discover the router port
dynamically. After a port is selected as the static router port, all IGMP Join and Leave
reports are forwarded to the port.
11.
Click the Apply button.
Your settings are saved.
Specify a VLAN for IGMP Snooping
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 27).
To specify a VLAN for 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.
If you do not know the IP address of the switch, see Access the Switch Using a Web
Browser on page 16.
