Parameter Description
Max Resp Time Maximum number of seconds to wait for a response to an
IGMP Query message before the group is deleted. The default
is 10 seconds with a range of 1 to 25.
Robustness Allows you to compensate for the expected packet loss on a
subnet. If the loss is expected to be high, increase the value.
The default is 2 and the range is 1 to 255.
Joins Number of multicast groups joined on this interface since it
was enabled. This parameter reflects the amount of IGMP
activity.
Wrong Queries Read-only. Number of queries received indicating that the
IGMP version does not match the Version value configured
on this interface. IGMP requires all routers on a network to be
configured to operate with the same version of IGMP. If any
queries indicate the wrong version, this indicates a
configuration error.
Groups Number of current IGMP groups joined on this interface.
Last Member A query is sent to determine if other hosts on the network
(Query) Interval wish to receive traffic from the multicast group. The Last
Query Interval is the time between queries. You can tune
this parameter to modify the leave latency of the network. A
reduced value results in reduced time to detect the loss of the
last member of a group. The parameter is ignored for Version
1 of IGMP. The default is 1 and the range is 1 to 25 seconds.
Version 1 Remaining time until the Cuda 12000 determines that no
Querier Timer IGMPv1 routers are present on the interface. When the value
is greater than 0, the host replies to all queries with IGMPv1
membership reports.
