Parameters
interface-type interface-number: Specifies the interface for which the current interface will act as the
IGMP proxy interface.
Description
Use the igmp proxy command to configure the current interface as the IGMP proxy interface for
another interface on the Layer 3 switch.
Use the undo igmp proxy command to restore the default.
No interface is configured as the IGMP proxy interface for another.
Before configuring the igmp proxy command on an interface, you must enable PIM on it. One interface
cannot serve as the IGMP proxy interface for two or more interfaces.
If the IGMP proxy feature is configured repeatedly on the same interface, the last configuration takes
effect.
