Enabling Multicast Source Port Filtering; Enabling Dropping Unknown Multicast Data - HPE FlexNetwork 5510 HI Series Configuration Manual

Enabling multicast source port filtering

This feature enables the 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.
You can enable this feature for the specified ports in IGMP-snooping view or for a port in interface
view. For a port, the configuration in interface view has the same priority as the configuration in
IGMP-snooping view, and the most recent configuration takes effect.

Enabling dropping unknown multicast data

Unknown multicast data refers to multicast data for which no forwarding entries exist in the IGMP
snooping forwarding table. This feature enables the device only to forward unknown multicast data to
the router port. If the device does not have a router port, unknown multicast data will be dropped.
If you do not enable this feature, the unknown multicast data is flooded in the VLAN to which the data
belongs.
Configuration restrictions and guidelines
When you enable dropping unknown multicast data, follow these restrictions and guidelines:
• You can enable this feature globally for all VLANs in IGMP-snooping view or for a VLAN in
VLAN view.
• The drop-unknown command in IGMP-snooping view and the igmp-snooping
drop-unknown command in VLAN view are mutually exclusive. You cannot configure them on
the same device.
