Enabling Multicast Source Port Filtering; Enabling Dropping Unknown Multicast Data - HP FlexFabric 5950 series Configuration Manual

Configuring a multicast group policy on a port
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Configure a multicast group
policy on the port.

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 multicast source port filtering in IGMP-snooping view
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable multicast source port
filtering.
Enabling multicast source port filtering in interface view
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Enable multicast source port
filtering.

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.
To enable dropping unknown multicast data in a VLAN or VSI:
Step
1. Enter system view.
