CLI – This example displays all the known multicast services supported on
VLAN 1, along with the ports propagating the corresponding services.
The type field shows if this entry was learned dynamically or was statically
configured.
Adding Multicast Addresses to VLANs
Multicast filtering can be dynamically configured using IGMP Snooping
and IGMP Query messages as described in “Configuring IGMP
Parameters” on page 2-72. For certain application 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 specific VLAN, the
corresponding traffic can only be forwarded to ports within that
VLAN.
Command Attribute
• Interface – Activates the Port or Trunk scroll down list.
• VLAN ID – Selects the VLAN to propagate all multicast traffic coming
from the attached multicast router/switch.
• Multicast IP – The IP address for a specific multicast service
• Port or Trunk – Specifies the interface attached to a multicast router.
