With this feature, you can filter multicast joins on a per-port basis by configuring IP
multicast profiles and associating them with individual switch ports. An IGMP profile can
contain one or more multicast groups and specifies whether access to the group is permitted
or denied. If an IGMP profile denying access to a multicast group is applied to a switch
port, the IGMP join report requesting the stream of IP multicast traffic is dropped, and the
port is not allowed to receive IP multicast traffic from that group. If the filtering action
permits access to the multicast group, the IGMP report from the port is forwarded for
normal processing.
IGMP filtering controls only IGMP membership join reports and has no relationship to the
function that directs the forwarding of IP multicast traffic.
Function name:
IGMP Snooping – Port Group Filtering
Function description:
The function is used to set the IGMP Port Group Filtering. With the IGMP filtering feature,
a user can exert this type of control. In some network Application environments, as like the
metropolitan or multiple-dwelling unit (MDU) installations, an user might want to control
the multicast groups to which a user on a switch port can belong. It allows the user to
control the distribution of multicast services, such as IP/TV, based on some type of
subscription or service plan.

used to calculate the Maximum Response Code inserted into
the periodic General Queries. The allowed range is 0 to
31744 in tenths of seconds; default query response interval
is 100 in tenths of seconds (10 seconds).
Last Listener Query Interval. The Last Listener Query
Interval is the Maximum Response Delay used to calculate
the Maximum Response Code inserted into Multicast
Address Specific Queries sent in response to Version 1
Multicast Listener Done messages. It is also the Maximum
Response Delay used to calculate the Maximum Response
Code inserted into Multicast Address and Source Specific
Query messages. The allowed range is 0 to 31744 in tenths
of seconds; default last listener query interval is 10 in tenths
of seconds (1 second).
Unsolicited Report Interval. The Unsolicited Report Interval
is the time between repetitions of a node's initial report of
interest in a multicast address. The allowed range is 0 to
31744 seconds; default unsolicited report interval is 1
second.
