4.8 IGMP Snooping
The Internet Group Management Protocol (IGMP) lets host and routers share information about multicast groups
memberships. IGMP snooping is a switch feature that monitors the exchange of IGMP messages and copies them to the
CPU for feature processing. The overall purpose of IGMP Snooping is to limit the forwarding of multicast frames to only
ports that are a member of the multicast group.
4.8.1 IGMP Snooping Configuration
The IGMP Configuration page let the administrator to configure the parameters for IGMP Snooping, which is used to build
forwarding lists for multicast traffic. The screen in Figure 4-34 appears.

• VLAN ID
Identifies a VLAN and contains information about the Multicast group configuration.
• IGMP Snooping
Enables or disables IGMP snooping on the VLAN. Ports be assign to the VLAN will be
• IGMP Querying
Enables or disables IGMP Query mode on the VLAN. The Query mode is used to
neighboring Multicast router/switch. Once IGMP Snooping is enabled, Multicast
packets are forwarded to the appropriate port .
Flooding Enable
Group streams to flood to all ports of this switch. The unregistered IP Multicast mea

Enabled is the default value. The switch forwards all the multicast steams to all the
host or linked switch.
Add a new VLAN group and the Table will add the VLAN entry automatically.
