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.
6.16.2.5 Assigning Ports to Multicast Services
Multicast filtering can be dynamically configured using IGMP Snooping and
IGMP Query messages as described in 6.16.2.1 "Configuring IGMP Snooping
and Query Parameters" 355. For certain applications that require tighter control,
it may be necessary to statically configure a multicast service on the ECN330-
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.
• Multicast IP – The IP address for a specific multicast service
• Port or Trunk – Specifies the interface attached to a multicast router.
