Layer 2 IGMP (Snooping and Query)
FIGURE 373 Showing Current Interfaces Attached a Multicast Router
Assigning Interfaces to Multicast Services
Use the Multicast > IGMP Snooping > IGMP Member (Add Static Member) page to statically assign
a multicast service to an interface.
Multicast filtering can be dynamically configured using IGMP Snooping and IGMP Query messages
(see
“Configuring IGMP Snooping and Query Parameters” on page 1093). 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.
CLI References
• “ip igmp snooping vlan static” on page 457
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.
Parameters
These parameters are displayed:
• VLAN – Specifies the VLAN which is to propagate the multicast service. (Range: 1-4093)
• Interface – Activates the Port or Trunk scroll down list.
• Port or Trunk – Specifies the interface assigned to a multicast group.
• Multicast IP – The IP address for a specific multicast service.
Interface
To statically assign an interface to a multicast service:
1. Click Multicast, IGMP Snooping, IGMP Member.
2. Select Add Static Member from the Action list.
3. Select the VLAN that will propagate the multicast service, specify the interface attached to a
multicast service (through an IGMP-enabled switch or multicast router), and enter the
multicast IP address.
4. Click Apply.
