The VoIP Gateway supports IGMP Snooping. This feature reduces the unnecessary use of
bandwidth by IP multicast traffic in LAN TV and other applications. If an IGMP querier
exists on the LAN, the VoIP Gateway can listen to the reports from the IGMP hosts to the
multicast router/querier and discover which multicast group hosts are connected to the VoIP
Gateway ports. It then maps the connections between multicast router/querier and multicast
group hosts. This enables the Gateway to direct multicast group traffic directly to the ports of
the hosts belonging to the multicast group, thereby eliminating traffic that has no mapped
destination.
NOTE
For EdgeGate 282/282S/482S/483S/483D products, when IGMP is enabled, the
Gateway uses VLAN IDs in the range 1792-1842 internally. Therefore, VLAN
IDs in this range should not be used by the user.
To enable control of the multicast traffic with IGMP:
In the vertical menu bar of the current VoIP Gateway Web page, select
IGMP.
The IGMP
Configuration page appears (
).
