10.3 IGMP Filtering

With the IGMP filtering feature, you can set which IGMP groups a subscriber on a port can
join. This allows you to control the distribution of multicast services (such as content
information distribution) based on service plans and types of subscription.
You can set the device to filter the multicast group join reports on a per-port basis by
configuring an IGMP filtering profile and associating the profile to a port.

DESCRIPTION
Select Enable_IGMP_Snooping to have the system passively learn multicast
groups.
Select Enable_IGMP_Proxy to have the system proxy multicast traffic.
Select Disable to have the system not use either IGMP proxy or snooping.
Select which version of IGMP you want the system to support. Select IGMPv2 (V2) or
IGMPv3 (V3). If you select IGMPv2, the system discards IGMPv3 packets. This
provides better security if none of the devices in the network use IGMPv3. If you
select IGMPv3, the system recognizes both IGMPv2 and IGMPv3.
Select Enable to enable IGMP fast leaving. In IPTV applications, this feature allows
user to quickly change video channels and enhances the user experience. See
Section 10.1.5 on page 195
Select Disable to turn this feature off.
Specify the time duration (0~256 seconds) the device requires to switch between two
video channels.
Type the number for an IGMP proxy VLAN and click Apply to add a static VLAN on
which the system sends IGMP query messages. This should be the number of a
subscriber VLAN. The VLAN will appear in the Static Query VID Table. You must
configure the system's VLAN settings before you can set static query VIDs.
This table lists the manually added VLANs on which the system sends IGMP query
messages. These are multicast service subscriber VLANs.
Click Delete to remove the selected entry.
This table lists the IGMP query VLANs that the system has dynamically learned via
IGMP snooping or IGMP proxy. These are VLANs on which the system sends IGMP
query messages. They are multicast service subscriber VLANs.
