3.6.5.Configuring IGMP Snooping Multicasting is used to support real-time applications such as video conferencing or
streaming audio. A multicast server does not have to establish a separate connection
with each client. It merely broadcasts its service to the network, and any hosts which
want to receive the multicast register with their local multicast switch / router. Although
this approach reduces the network overhead required by a multicast server, the
broadcast traffic must be carefully filtered at every multicast switch / router it passes
through to ensure that traffic is passed on only to the hosts which subscribed to this
service.
This switch uses IGMP (Internet Group Management Protocol) Snooping to monitor for
any attached hosts who want to receive a specific multicast service. It looks up the IP
Multicast Group used for this service, and adds any port which received a similar
request to that group.
You can use the IGMP Snooping Configuration screen to configure multicast filtering as
shown below.
Parameter Default Description
IGMP
Snooping
Status¹
Disabled If enabled, the switch will monitor network traffic to determine
which hosts want to receive multicast traffic. This is also
referred to as IGMP Snooping.
IGMP Router
Timeout

this interval will be removed from the IGMP forwarding list.
Range: 3 - 5 minutes
IGMP Group
Timeout
