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. Command system-view igmp-snooping 3. Configure a multicast group filter. group-policy acl-number [ vlan vlan-list ] 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. 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. Command system-view interface interface-type interface-number 3. Configure a multicast group filter. igmp-snooping group-policy acl-number [ vlan vlan-list ] 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. 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. Command system-view igmp-snooping source-deny port interface-list Remarks N/A N/A Disabled by default 27
