IGMP Proxy:
IGMP proxy enables the switch to issue IGMP host messages on behalf
of hosts that the system discovered through standard IGMP interfaces.
The system acts as a proxy for its hosts. This switch can be set IGMP
function “Enable” or “Disable” by VLAN group. If the VLAN group
IGMP proxy is disabled, the switch will stop the exchange of IGMP
messages in the VLAN group members. If the VLAN group IGMP proxy
is enabled, the switch will support the exchange of IGMP messages in
the VLAN group members and follow up IGMP proxy router port
configuration, which connects to a router closer to the root of the tree.
This interface is the upstream interface. The router on the upstream
interface should be running IGMP. You enable IGMP on the interfaces
that connect the system to its hosts that are farther away from the root of
the tree. These interfaces are known as downstream interfaces. Please
refer to 3-15-1 for detail IGMP Proxy function description.
