Description
The adjustable field (LMQC) allows to set the
number of counts of next parameter
"LastMemberQueryInterval", for the IP Router,
before it establishes that no other member of
this IGMP group is present and thus removing
the multicast transmission.
The possible values are "enabled" or
"disabled".
enable means that this VLAN delegates the
•
Node (acting as Proxy) to report to the
Router one summarized collective
message, together with the other VLAN's
involved in the same IGMP group.
disable means that this VLAN is not
•
interested in the collective Proxy reporting.
In this case all the reports from the
members of the IGMP group are forwarded
transparently to the router.
The adjustable field (LMQ) allows to set the
time interval, for the IP Router, between the
queries sent from the Router to the users, to
check if any other member is present on this
IGMP group.
The product of the two previous
Note:
parameters (LMQC*LMQI) gives the time, for
the IP Router, to establish that no other member
of this IGMP group is present and thus
removing the multicast transmission.
The entry field allows to digit the amount of
time (in sec.) after which the IP router can
check if no other member of this IGMP group is
interested in the multicast transmission, if no
Report from users is sent in this interval.
The possible values are:
V1: It supports the IGMP Query from the
•
Router and the Reports from users.
V2: It supports, in addition to V1 features,
•
the fast leave of a user from the IGMP
group.
The entry field allows to digit the time interval
(in sec.) for the node for dynamic refresh of the
list of existing IP Multicast Routers. After this
time, not alive Routers are deleted from the
list.
