hosts in VLANs can join any 
valid multicast group. 

 

Follow these steps to configure a multicast group filter on a port or a group of ports:  

Enter system view 

system-view

Configure a multicast group 
filter  

igmp-snooping group-policy 
acl-number [ vlan vlan-list ] 

Required 

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

 

With the multicast source port filtering feature enabled on a port, the port can be connected with 

multicast receivers only rather than with multicast sources, because the port will block all multicast data 

packets while it permits multicast protocol packets to pass.  

If this feature is disabled on a port, the port can be connected with both multicast sources and multicast 

receivers.  

Follow these steps to configure multicast source port filtering globally:  

Enter system view 

system-view 

— 

Enter IGMP snooping view 

— 

Enable multicast source port 
filtering  

source-deny port interface-list

Required
