Configuring Multicast Source Port Filtering - HP 6125G Configuration Manual

Configuration guidelines
When you configure a multicast group filter in a multicast VLAN, be sure to configure the filter in the
•
sub-VLANs of the multicast VLAN. Otherwise, the configuration does not take effect.
• In IGMPv3, when a host is enabled to join multiple multicast groups, the multicast group filter
cannot correctly filter multicast groups because the host that runs IGMPv3 sends multiple multicast
groups that it wants to join in one membership report.
Configuration procedure
To configure a multicast group filter globally:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Configure a multicast group
filter.
To configure a multicast group filter 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
filter.

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
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable multicast source port
filtering.

Remarks
N/A
N/A
By default, no group filter is
globally configured. That is, the
hosts in a VLAN can join any valid
multicast group.
Remarks
N/A
Use either command.
By default, no group filter is
configured on the current port. That
is, the hosts on this port can join
any valid multicast group.
