Configuring static joining
After an interface is configured as a static member of a multicast group or a multicast source group, it will
act as a virtual member of the multicast group to receive multicast data addressed to that multicast group
for the purpose of testing multicast data forwarding.
Follow these steps to configure an interface as a statically connected member of a multicast group or a
multicast source and group:

Required
An interface is not a static member
of any multicast group or multicast
source and group by default.
NOTE:
•
Before you can configure an interface of a PIM-SM switch as a static member of a multicast group or a
multicast source and group, if the interface is PIM-SM enabled, it must be a PIM-SM DR. If the interface
is enabled with IGMP but not with PIM-SM, it must be an IGMP querier. For more information about
PIM-SM and DR, see the chapter “PIM configuration.”
• A static member port does not respond to queries from the IGMP querier. When you configure a port as
a static member port or remove this configuration on the port, the port does not unsolicitedly send any
IGMP report or IGMP leave message. In other words, the port is not a real member of the multicast
group or the multicast source and group.
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
the match the criteria.
Follow these steps to configure a multicast group filter:
