Command Mode:

Example:
Switch(config)#ip igmp proxy limit group 30 source 20
44.11.11 ip igmp proxy multicast-source
Command:
ip igmp proxy multicast-source
no ip igmp proxy multicast-source
Function:
To configure the port as downstream port for the source of multicast datagram; the no from of this
command disables the configuration.
Command Mode:

Default:
The downstream port is not for the source of multicast datagram.
Usage Guide:
When a downstream port is configured as the multicast source port, the switch will be able to
receive multicast data flow from that port, and forward it to the upstream port. To make this
command function, the multicast router which is connected to the upstream port of the switch,
should be configured to view the multicast source from the upstream port is directly connected to
the router.
Example:
Enable igmp proxy multicast-source in downstream port VLAN1.
Switch (config)#interface vlan 1
Switch (Config-if-Vlan1)#ip igmp proxy multicast-source
