IGMP
IGMP, known as Internet Group Management Protocol, is used to manage hosts from multicast
group.
IGMP Proxy: IGMP proxy enables the system to issue IGMP host messages on behalf of the
hosts that the system has discovered through standard IGMP interfaces. The system acts as a
proxy for its hosts. Default is set to Disable.
IGMP Snooping: Allows a layer 2 switch to manage the transmission of any incoming IGMP
multicast packet groups between the host and the router. Default is set to Disable.
Click Apply to confirm the settings.
Example:
When IGMP snooping is enabled, the feature will analyze all incoming IGMP packets between the
hosts that are connected to the switch and the multicast routers in the network. When the layer 2
switch receives an IGMP report from a host requesting for a given multicast group, the switch will
add the host's port number to the multicast list for that multicast group to be forwarded to. And,
when the layer 2 switch has detected that an IGMP has left, it will remove the host's port from the
table entry.
