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.
Assigning Ports to Multicast Services
Multicast filtering can be dynamically configured using IGMP Snooping and IGMP
Query messages as described in “3-163. 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
• 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/switch.
