Configuring a Multicast Group Filter
To restrict the hosts on the network attached to an interface from joining certain multicast groups, you can
set an ACL rule on the interface as a packet filter so that the interface maintains only the multicast groups
matching the criteria.
Follow these steps to configure a multicast group filter:
To do... Use the command... Remarks
Enter system view system-view —
Enter interface view
interface interface-type
interface-number
—

[ version-number ]
Required
By default, no multicast group filter
is configured on this interface,
namely hosts on the current
interface can join any valid
multicast group.
Configuring the Maximum Number of Multicast Groups on an
Interface
You can configure the allowed maximum number of multicast groups on an interface to flexibly control
the number of multicast groups the interface can join.
Follow these steps to configure the maximum number of multicast groups an interface can join:
