IGMP Snooping
The switch can use Internet Group Management Protocol (IGMP) to filter
multicast traffic. IGMP Snooping monitors IGMP service requests passing
between multicast clients and servers, and dynamically configures the ports
which need to receive the multicast traffic.
You can configure the switch to forward multicast traffic intelligently.
Based on the IGMP query and report messages, the switch forwards traffic
only to the ports that request multicast traffic. This prevents the switch
from broadcasting the traffic to all ports and possibly disrupting network
performance.
This switch can passively snoop on IGMP query and report packets
transferred between IP multicast routers/switches and IP multicast host
groups to identify the IP multicast group members. It simply monitors the
IGMP packets passing through it, picks out the group registration
information, and configures the multicast filters accordingly.
Note:
For IGMPV3, the switch incudes basic support for reports only,
Source Multicast is not supported.
Configuring IGMP Snooping and Query Parameters
Use the IGMP Snooping Configuration page to enable or disable IGMP
snooping, to designate the ports attached to multicast routers, and to
enable or disable flooding of unknown multicast traffic.
