Enabling multicast source port filtering

About multicast source port filtering

This feature enables the Layer 2 device to discard all multicast data packets and to accept multicast protocol packets. You can enable this feature on ports that connect only to multicast receivers.

Restrictions and guidelines

When multicast source port filtering is enabled, the system automatically enables IPv6 multicast source port filtering.

The configuration made for multiple interfaces in IGMP-snooping view has the same priority as the interface-specific configuration, and the most recent configuration takes effect.
