Configuring multicast source port filtering

When the multicast source port filtering feature is enabled on a port, the port can connect to only
multicast receivers rather than to multicast sources, because the port blocks all multicast data packets but
it permits multicast protocol packets to pass.
If this feature is disabled on a port, the port can connect to both multicast sources and multicast
receivers.
Configuring multicast source port filtering globally
Follow these steps to configure multicast source port filtering globally:

Configuring the function of dropping unknown multicast data

Unknown multicast data refers to multicast data for which no entries exist in the IGMP snooping
forwarding table. When the switch receives such multicast traffic, one of the following occurs:
When the function of dropping unknown multicast data is disabled, the switch floods unknown
•
multicast data in the VLAN that the unknown multicast data belongs to, causing network bandwidth
waste and low forwarding efficiency.
Use the command...
igmp-snooping group-policy acl-

Remarks
Required
By default, no group filter is
configured on the current port.
That is, the hosts on this port can
join any valid multicast group.
