Assigning Ports to Multicast Services
Multicast filtering can be dynamically configured using IGMP Snooping
and IGMP Query messages as described in “Configuring IGMP snooping
and Query Parameters” on page 3-133. For certain applications that
require tighter control, you may need to statically configure a multicast
service on the switch. First add all the ports attached to participating hosts
to a common VLAN, and then assign the multicast service to that VLAN
group.
Command Usage
•
Static multicast addresses are never aged out.
•
When a multicast address is assigned to an interface in a specific
VLAN, the corresponding traffic can only be forwarded to ports
within that VLAN.
Command Attributes
