Figure 332: Showing Static Interfaces Attached an IPv6 Multicast Router
To show all the interfaces attached to a multicast router:
1.
Click Multicast, MLD Snooping, Multicast Router.
2.
Select Current Multicast Router from the Action list.
3.
Select the VLAN for which to display this information. Ports in the selected
VLAN which are attached to a neighboring multicast router/switch are
displayed.

Use the Multicast > MLD Snooping > MLD Member (Add Static Member) page to
statically assign an IPv6 multicast service to an interface.
Multicast filtering can be dynamically configured using MLD snooping and query
messages (see
"Configuring MLD Snooping and Query Parameters" on page
However, for certain applications that require tighter control, it may be necessary 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.
